That's a very nice feature. I have one on a Warmoth Tele neck and it makes adjusting the neck very easy, so precise adjustments are possible. I wish more things in my life had a side adjustment mechanism.
I have owned a Warmoth guitar with one of these truss rods for about 10 years and have only had to adjust it once, unlike some of my other (high end) guitars that need adjusting about twice a year on average. Thanks Warmoth!
They make really good stable necks even if you have the Vintage style with single adjustment at the heel. I think a little more pride and care goes in than with Fender USA necks and bodies.
Plus it being a fine adjustment, and plus it being adjustable under string tension… I’m less afraid of these things now, even though I’m totally fine with the simpler Vintage design the company also make… my Warmoth neck just never moves! (And this despite having the neck back lacquer sanded off and just oil and wax applied… that’s a good chunk of maple right there.)
This is by far the best design I’ve ever used. I’ve build a dozen guitars with your modern necks and I joke that the torsion rods on them are “set and forget.” Very mechanically stable.
Would love to see an install video for one of these. Would you advise making any adjustments before installation to save some time? or just pop it on a guitar and see if it needs major or minor adjustment from there?
All my necks are warmoth pro necks with the side adjust, I love it. Anyone saying that they "rob tone" wouldn't know tone if it smacked them in the face because chances are they are running 99 effects on their digital modeling amp computer software (to hide their screw ups). why can't anyone play with a simple jack cord straight into a Marshall anymore??? That's tone!!!!!
Lol I play with the simplest setup I can, I have always hated too much going on as far as effects go. I have some stuff that sit on a shelf with zero use (wah pedal, effect processor) both collect dust. I rely on pickup selection, a pedal I built for distortion (freidman-BEOD circuit with modifications to the diodes and caps used to soften the 4 gain stages in the circuit with a true bypass to get to the actual sound of my clean channel) and a Blackstar tube amp on clean with everything zeroed. It was the simplest setup I could do and get tones from the 50's all the way to now. Sometimes I will use the boost on the amp. The pickups has always been where I adjust tone and sometimes the electronics of the guitar itself so it causes me to have 2 guitars with actives from both Seymour Duncan and EMG but I got a strat with vintage noiseless in them (still can't get passed the 60HZ hum) and a couple of odd passives in a couple of odd guitars. I still feel the tonal quality of a guitar is found in the instrument and how well it is built and how well it is tailored to the person using it. Nuno Bettencourt is a prime example of a person who tailored their guitar from parts to himself. I am with you I do not consider a computer modeler an amp, it is a virtual practice amp and should always be treated as such. It can produce clean sounds and some are unique enough I actually like them but it still does not compare to the sound obtained by an actual amp guitar and a good player. There is no way that tiny thing that uses a brass containment block (which should be tonally ideal) robs tone, if a person says it does they have sloppy playing. But then again I am a person who finds guitarists like Slash or David Gilmore are great guitarists, not because of technical ability but because they play the shit out of their guitars.
You've just described my favorite guitar tone; Guitar/Mogami Gold Cable into 2203 Marshall...COOKED! Some kid asked me how I got my tone after a show once, I handed him a guitar cable, and laughed, he was amazed.
The bullet truss rod system would seem to eliminate the need for a micro adjustment since it seems to be a workaround to having to take the neck off to adjust the trussrod. So why not go with that/ Is it the mass taken from the base of the neck, rather than closer to the headstock where most people play?
OH! wow, now I get it. It's really analogous to the fine tuners of a FLoyd Rose system. Instead of taking the guitar neck off each time to adjust you can just get it close with the main one and then use the side one to fine tune it after you get the guitar all back together and tuned up. More of a time saver I guess.
Oh, so that’s how those work! I hadn’t realized there were two adjustment points and had figured there were some bevel gears in there or something. Neat!
I've got a replacement strat neck like this one from Warmouth in 2011. It is the best strat neck I have ever played, IMHO. I did fret leveling and recrowning myself to my preferences with a bone nut from scratch. The best purchase I have ever made for a guitar part. Now, I am considering a complete warmouth Telecaster "build" to my exact preferences.
But if you had to level the frets, or at least lower the height of them to you taste, then the neck definitely is not the best strat neck you have ever played. Couldn't you have ordered one with frets the height of which you liked? Warmoth has great illustrations of the specs of their necks. Very specific. Why, specifically, was this the best strat neck you every played? What made it so, specifically?
So the Flat Bar of the truss rod, which is closest to the fretboard, actually bends the neck against the string tension? so technically loosening the truss rod would allow the subtle curve of the neck, where as tightening it would straighten the neck? is that opposite of standard truss rods?
Bought one recently just like you showed as your example neck. Had no clue what that side adjust was but now it all makes good sense thanks for the video! Off to mount up! Blues On!!! :)
I have one on my guitar neck from warmoth. Just imagine you set the neck prior to installation, then you install and string it up, the strings apply a little bit of tension and bow your neck a bit out of what you had it, this allows you to minor adjust it back, it's an ingenious idea and anybody who doesn't like it is being a curmudgeon. I have been playing since 81 and wish I had this before.
So am I : I think Warmoth double-expanding truss-rod IS NOT a two-way truss rod, so if your neck is severly back bowed, the truss rod can't force the neck to go in the other way to fix the problem...
@@gloubiboulgazeblob - this is technically correct, however in a properly made neck the string tension is all you need opposing the single-action truss rod… I would imagine backbow is likely super rare. Otherwise warranty should cover?
I mistakenly thought that a double truss rod could make the neck curve either way. IOW force relief (actually counteract excessive backbow) as well as produce backbow. However, this demonstration indicates that the double truss rod is only capable of producing backbow to counteract string tension. If that is the case, the benefits appear to be 1) pressure from adjusting nut is metal on metal (instead of metal on wood), and 2) truss rod channel is a simple, flat bottomed dado of sorts instead of the convex channel require for a single stress rod. Is that correct? Question: are fingerboards thinner, thicker, or the same with a double truss rod? A regular, single-action truss rod applies pressure to the body of the neck. Here it looks like the double action truss rod applies pressure to the underside of the fingerboard, but I may be mistaken.
Aaron, I'd love to see a tutorial on what your instructions say when you receive your neck with the double truss rod. It explains how to set the truss rod. I'll be honest, I never could figure out what the hell that meant so I just left it alone. Luckily none of my Warmoth guitars have needed adjusting, because I didn't set anything, I just took it out of the box and put it on the guitar. A detailed tutorial on that one would be VERY helpful.
The Warmoth double-truss rod bends in a single direction, by the use of two different bars anchored to each other. On traditional single truss rods, the bar is anchored to the neck wood itself. There are certain rods that flex in both directions, sometimes called "bi-flex" truss rods, but Warmoth does not use them.
@@prd004.2 Of course, but wood is a strange animal. It reacts to climate and humidity in ways that can cause it to twist and warp in any direction really. The tension capable of being applied from a truss rod is orders of magnitude greater than the tension coming from the strings, even if heavy gauge strings are used. And if the player is using 9s or lighter, on a 25.5" scale guitar, with no wound third, that's barely any tension at all.
@@5urg3x Nick, great response. Love my Warmoth neck, but could REALLY use some neck relief. With 9s or 10s, there is really not enough tension to provide relief. Otherwise, the neck just lays flat, requiring sting action to be a bit higher than preferred. And, I have a wenge next that appears to have less "give" than typical neck woods.
Great video. The cut-away neck really makes it all clear. I must admit that I previously misunderstood the "double truss rod" concept, thinking that the adjustment could produce either convex or concave fingerboard shapes. Can you confirm that the action is in a single sense (counteracting the effect of the strings) but achieved by the different tension in two rods?
+Mark Thomas: You are correct. The Warmoth double-truss rod bends in a single direction, by the use of two different bars anchored to each other.

Thanks for the informative video. Just a note: Those "welds" on the end of the double truss rod appear to be "brazed joints" which technically isn't a welding process as defined by the AWS (American Welding Society.)
5:39 Until NECKS time, man. Sorry to say, but this side adjustment mechanism looks like a solution in search of a problem. If you just put the nut on the headstock end, there is no need to take the neck off to access the truss rod. When tweaking the truss rod, you want the strings to be on and in tune, so you can directly monitor the effect on playability and make immediate secondary adjustments like saddle and pickup height, and instantly try everything together.
RIGHT? Why any guitar manufacturer still produces necks with the truss rod adjustment nut at the goddamn heel is beyond me. Just put it on the headstock, ffs! Lol
@@INeverWanted2010 supposedly it makes for a more stable neck and less chance of the headstock breaking off. however the best solution is the spoke wheel heel adjustment imo.
Great video and I learned a lot. I've only been playing since 1966 but I thought the only problem with single truss rods was that some are adjusted at the wrong end. No wonder Leo didn't want to use them. But since I haven't had trouble with old fashioned truss rods, and this double type still only goes one way (good joke, right there) I'm wondering how much weight the double rod and adjustment box add to the neck?
hi .my question is how to bend the rod(neck) to the other direction if needed? it looks we can only bend the rod( neck) to one direction which I still do not know which side it bends when we tight the nut. but if we lose the nut the rod will be only stright. and does not go to the other direction. what is the solution then?
So..there's a two way truss rod and a double truss rod. The double truss rod is not a two way..correct? It seems that the side adjust would exert more force than the side adjust. Can you please explain why I'm thinking wrong? Thank you! I understand that a screw is a rotary inclined plane, and the side adjust is an inclined plane.
I read that you have to loosen the strings before turning the side adjustment screw. How critical is this? Do I have to loosen them all the way, or can I just dump the whammy and slacken the strings that way? What damage does it cause if you adjust it without loosening the strings first?
A bit off the subject on this device, from what l understand or told, PRS even the SE model are equipped with double acting truss rod is this true, and is it better than a single acting truss rod? Thanks again...?
One thing I don't quite understand - with the side adjust box installed between the adjustment nut and the bar, you show how it is still possible to make major adjustments using the nut. That makes sense, but won't it also push the side adjust box position toward the bar as well? But since the access to the side adjust mechanism is drilled through the side of the neck heel, I would think the box has to stay where it is, right? Or is the movement so small that it will always basically line up with the access point on the side of the neck?
If I understand well a double-expanding truss rod IS NOT a two-way truss rod, right ? With a double-expanding truss rod, like in a Warmoth Super Bass neck , one can only tightens the truss rod to make a back bow, going counter-clockwise can only bring the truss rod back to its "neutral" position, right ?
@@warmoth Oh, I've got one question to ask : what's best to do if a Warmoth Super Bass neck is removed and unused for a long period ? Should I unscrew the truss rod until its nut is loose or should I tighten just a little bit ?
hi I'm replacing a trussrod on a strat with a double action one. I'm pretty sure that smartest way to go about it is to have the trussrod put in a way that when you turn to the right, thus pull on the flatbar of the trussrod it relieves the guitar neck, (in my case, forces the neck to relief) wouldn't you agree? My strat has a pretty stubborn backbow, so much so that the biflex system of fender caused the plug at the headstock to pop out
thank you faor sharing this vidoe , I am instrument maker , But not Guitar , I liked your clear explanation for the echanism , It was my question how it works .
Warmoth is the best, I have a Warmoth pro maple birdseye neck with side adjustment, it's incredibly stable and feels great! I wouldn't want any other neck ever!
I bought a custom neck with the side adjust mechanism and I love how it works. The problem is I can’t find a side adjust anywhere else, Gotoh seems to have discontinued it. Any idea where to buy just the side adjust mechanism?
Way to go Aaron! Great explanation of an excellent truss rod adjustment system. Might I add that we're all pleased no kids or pets were hurt during the making of this video. LOL!
How far from the side of the neck and how far from the base of the heel to the side adjust mechanism? I'm about to drill a hole into the neck but don't want to drill into the mechanism.
I broke side adjusting screw a couple years ago. I dumped the whammy while adjusting but the screw was broken and fell out. Now adjustment is only at heel. The neck is still ok. But this mechanism is not durable... ((
What's the size of that allen key for the Side Adjustment Mechanism? I'm in Sweden and can't find one that fit snugly ! I've got several that's close but I would rather have one that fits perfectly !
I have a question I have an Esquire so I have access to either of the neck adjustment screws. does it matter which one I use can I use the main one all the time. And also this is a great neck the best neck I've ever played on
the issue with my neck was that the frets weren't leveled properly, i always thought my schaller floyd rose bridge wasn't leveled, or the truss wasn't properly adjusted. not sure when i bought mine, i think around 2009 surprised that you guys have a youtube channel now lol
I'm a welder, and I thought the same thing. Prob has something to do with the amount of heat involved and how much said heat distorts the metal. But I'd like to know
Most of the truss rods I have seen appear to be tig welded or actually "spot" tig welded. As for the strength of the brazed joints? It's strong enough to do the job and that is all that matters.
Super helpful! I just received a Strat superwide replacement neck yesterday with this feature. How do you recommend setting the action on the neck before you bolt it to the guitar and string it?
That is cool but it's still somewhat limited. It seems to me that the adjustment nut at headstock or musicman type adjustment at heel are better options because you can make even major adjustments without removing the neck
Very Cool Necks I own 3... The Only thing That wasn't mentioned is the Side Adjustment is 3 mm/ metric. I've never had to Adjust any necks till now I need to adjust the Tele neck. !/4 turn should do it That's it. I'm using the back adj screw. with a straight edge stainless steel flat stock. To bow the neck upward clock wise turn. To curve it counter clockwise. Enjoy.. < concave neck adjustment .
One of these came with my warmoth neck which is the best damn neck I Ever owned, this is a great device and I would strongly recommend it the problem is I never have to use it because the neck is so damn good
Amazing tutorial! I never really understood how the truss rod worked. but here is a question, when you tighten the rod , what part of the neck moves to change the string gap? just the fret board? or does it somehow make the whole neck move? please explain what the rod moves thank you !!!
Awesome!!... A question- if i live in a climate where frequent adjustments are a possibility, would it be a good idea to halfway engage the side adjustment so I have the flexibility to tighten or loosen the truss rod without taking off the neck?
Yes, but it's not "a good idea", what you described is simply the universal starting point for this type of neck. Living in a climate change zone doesn't affect the method of adjusting the instrument, at most It affects how many times you have to adjust it.
I reading that Gotoh has discontinued these? I haven’t been able to locate them on Warmoth’s site either (unless I’m missing something). I’m looking to use one in an upcoming neck build… any advice?
i thought that if you relax the truss rod, the string tension would make the neck concave, and if you tightened the truss rod,the neck becomes more staight. The string tension doesn't play a role ?
You are correct, and string tension definitely plays a role. I think the thing that is throwing you off is the fact that when a double truss rod is at rest, it is straight. Imagine a brand new neck. The truss rod is sitting in that neck, chilling, at rest, and straight. Then you put string tension on the neck, and the strings start pulling the headstock towards the body, and neck begins to bow. But.....the truss rod is still just sitting in there, relaxing, doing nothing. It is still, essentially, straight. It's made of steel, so of course it is providing some counter-force just by virtue of the fact that it is naturally more rigid than wood is...but it's still not actively doing anything. In order to provide the force necessary to counter the tension of the strings you have to tighten the rod. When you do this, the rod starts to bow in the opposite direction of the neck, exerting downward pressure at the headstock end, which pulls the neck back towards straight. To put it another way: the truss rod pulls the neck back towards straight by bending in the opposite direction. To be clear: this explanation *only* applies to double truss rods. Traditional single-style rods work differently.
I wonder if i can use it as a replacement for an American deluxe strat, I dunno if the offset screw (elite-deluxe models) is going to work well with the side Adjustment Mech!! Thanks #Warmoth Guitar Products
Different string gauges will exert more or less force on the neck, depending on whether you are going up or down in size. That means you may need to tweak the truss rod a bit to get things exactly how you want them. Not necessarily, though. If it were me, I would play with the new gauge for a while and wait to observe any changes before jumping in and making adjustments.
Yes. The point is you can make rod adjustments without having to mess with the strings. I've never had to use the major adjust at the heel with any of my many Warmoth necks.
This is by far the best truss rod mechanism explanation I have ever seen (side mechanism or not). Great video!

It's why I use Warmoth necks for my bolt on guitars I have made for myself. Solid necks.
Great video and I learned a lot. I've only been playing since 1966 but I thought the only problem with single truss rods was that some are adjusted at the wrong end. No wonder Leo didn't want to use them. But since I haven't had trouble with old fashioned truss rods, and this double type still only goes one way (good joke, right there) I'm wondering how much weight the double rod and adjustment box add to the neck?
Straight and to the point. No pun intended. Thanks man
hi .my question is how to bend the rod(neck) to the other direction if needed? it looks we can only bend the rod( neck) to one direction which I still do not know which side it bends when we tight the nut. but if we lose the nut the rod will be only stright. and does not go to the other direction. what is the solution then?
WOW. a Satisfactory Explanation of a truss rod. Thanks for making the vid :)
Great video , the cutaway helps in seeing how it all works!
So..there's a two way truss rod and a double truss rod. The double truss rod is not a two way..correct?
It seems that the side adjust would exert more force than the side adjust. Can you please explain why I'm thinking wrong? Thank you!
I understand that a screw is a rotary inclined plane, and the side adjust is an inclined plane.
The great explanation about truss rod in the world
I read that you have to loosen the strings before turning the side adjustment screw. How critical is this? Do I have to loosen them all the way, or can I just dump the whammy and slacken the strings that way? What damage does it cause if you adjust it without loosening the strings first?
Dumping the whammy works fine. I do it all the time. The idea is to relieve the pressure on the mechanism while make the adjustment.
The side adjust Allen is 3mm but what Allen size do I need for the main adjustment at the end of the neck?
A bit off the subject on this device, from what l understand or told, PRS even the SE model are equipped with double acting truss rod is this true, and is it better than a single acting truss rod? Thanks again...?
One thing I don't quite understand - with the side adjust box installed between the adjustment nut and the bar, you show how it is still possible to make major adjustments using the nut.
That makes sense, but won't it also push the side adjust box position toward the bar as well? But since the access to the side adjust mechanism is drilled through the side of the neck heel, I would think the box has to stay where it is, right? Or is the movement so small that it will always basically line up with the access point on the side of the neck?
If I understand well a double-expanding truss rod IS NOT a two-way truss rod, right ?
With a double-expanding truss rod, like in a Warmoth Super Bass neck , one can only tightens the truss rod to make a back bow, going counter-clockwise can only bring the truss rod back to its "neutral" position, right ?
This is correct. The Warmoth rod is not a "bi-flex" rod. Rather, it flexes in one direction only, by using two metal shafts.
@@warmoth Thanks
@@warmoth Oh, I've got one question to ask : what's best to do if a Warmoth Super Bass neck is removed and unused for a long period ? Should I unscrew the truss rod until its nut is loose or should I tighten just a little bit ?
hi I'm replacing a trussrod on a strat with a double action one. I'm pretty sure that smartest way to go about it is to have the trussrod put in a way that when you turn to the right, thus pull on the flatbar of the trussrod it relieves the guitar neck, (in my case, forces the neck to relief) wouldn't you agree? My strat has a pretty stubborn backbow, so much so that the biflex system of fender caused the plug at the headstock to pop out
thank you faor sharing this vidoe , I am instrument maker , But not Guitar , I liked your clear explanation for the echanism , It was my question how it works .
Very clear explanation now I understand how a truss rod works
Say I'm using 10s, tuned down a half-step, on a 24.75" scale neck...is a Modern / side-adjust neck going to have ANY relief?
Warmoth is the best, I have a Warmoth pro maple birdseye neck with side adjustment, it's incredibly stable and feels great! I wouldn't want any other neck ever!
I bought a custom neck with the side adjust mechanism and I love how it works. The problem is I can’t find a side adjust anywhere else, Gotoh seems to have discontinued it. Any idea where to buy just the side adjust mechanism?
AFAIK Gotoh makes them for us exclusively at this point.
I was hoping to learn how to initially set one up before installing the neck on my guitar.
Way to go Aaron! Great explanation of an excellent truss rod adjustment system. Might I add that we're all pleased no kids or pets were hurt during the making of this video. LOL!
Got a cuestion, why can't I find a "warmoth neck finishes" video?
How far from the side of the neck and how far from the base of the heel to the side adjust mechanism? I'm about to drill a hole into the neck but don't want to drill into the mechanism.
I broke side adjusting screw a couple years ago. I dumped the whammy while adjusting but the screw was broken and fell out. Now adjustment is only at heel. The neck is still ok. But this mechanism is not durable... ((
What's the size of that allen key for the Side Adjustment Mechanism?
I'm in Sweden and can't find one that fit snugly !
I've got several that's close but I would rather have one that fits perfectly !
Sizes are listed here: warmoth.com/wrench-modern-set
Yet, which necks is this Side Adjustment Mechanism available on?
So if my neck is bending towards the middle of my fretboard, what do I do? It looks like tightening this would make it worse.
Really cool video. It's about time we got to the 21st century with that idea.
Do you have a Video on, " How to determine Which Neck Shape Fits YOUR HAND SIZE, BEST: C, V, D, etc. ? "
There is this one: ua-cam.com/video/QndUvW8cNTo/v-deo.html
An excellently explained video
Very cool mechanism. So much easier to use than the conventional headstock adjustment system.
I have a question I have an Esquire so I have access to either of the neck adjustment screws. does it matter which one I use can I use the main one all the time. And also this is a great neck the best neck I've ever played on
the issue with my neck was that the frets weren't leveled properly, i always thought my schaller floyd rose bridge wasn't leveled, or the truss wasn't properly adjusted.
not sure when i bought mine, i think around 2009
surprised that you guys have a youtube channel now lol
it appears that you are brazing the two rods together. Wouldn't it be better to MIG weld them which should be a stronger weld ?
I'm a welder, and I thought the same thing. Prob has something to do with the amount of heat involved and how much said heat distorts the metal.
But I'd like to know
@@prd004.2Maybe and that's a big maybe, the material use for braising has a noise dampening effect on the truss rod.
Most of the truss rods I have seen appear to be tig welded or actually "spot" tig welded. As for the strength of the brazed joints? It's strong enough to do the job and that is all that matters.
The awesome display of info helped me to decide on choosing a neck. thanks !!
Does this affect the resonance of the neck with that much more metal instead of wood?
Super helpful! I just received a Strat superwide replacement neck yesterday with this feature. How do you recommend setting the action on the neck before you bolt it to the guitar and string it?
That is cool but it's still somewhat limited. It seems to me that the adjustment nut at headstock or musicman type adjustment at heel are better options because you can make even major adjustments without removing the neck
I own or have owned over 10 of these necks. I have NEVER had to use the heel major adjust nut.
Great video. What size wrench is used for the side adjustment??
Sizes are listed here: warmoth.com/wrench-modern-set
@@warmoth Thank you!!
Very Cool Necks I own 3... The Only thing That wasn't mentioned is the Side Adjustment is 3 mm/ metric. I've never had to Adjust any necks till now
I need to adjust the Tele neck. !/4 turn should do it That's it. I'm using the back adj screw. with a straight edge stainless steel flat stock.
To bow the neck upward clock wise turn. To curve it counter clockwise. Enjoy.. < concave neck adjustment .
I very much prefer the barrel adjuster on my Music Man Silhouette neck. I do like the idea of the side adjust.
One of these came with my warmoth neck which is the best damn neck I Ever owned, this is a great device and I would strongly recommend it the problem is I never have to use it because the neck is so damn good
Amazing tutorial! I never really understood how the truss rod worked. but here is a question, when you tighten the rod , what part of the neck moves to change the string gap? just the fret board? or does it somehow make the whole neck move? please explain what the rod moves thank you !!!
The whole neck moves.
Is the side adjustment mechanism available with truss rods that are adjusted at the headstock end?
Nope. It's only available on Modern Construction necks, which have the truss adjust at the heel.
You should make a video showing how to fix the side adjuster if you unscrew the allen too far
It stops moving about 8 turns before the screw comes out. Should never happen. You can actually feel the lack of resistance
@@1seriousgearheadify If it gets screwed in too far, It can be a real problem.
Great video, I love Warmoth
Awesome!!... A question- if i live in a climate where frequent adjustments are a possibility, would it be a good idea to halfway engage the side adjustment so I have the flexibility to tighten or loosen the truss rod without taking off the neck?
Yes, but it's not "a good idea", what you described is simply the universal starting point for this type of neck.
Living in a climate change zone doesn't affect the method of adjusting the instrument, at most It affects how many times you have to adjust it.
I reading that Gotoh has discontinued these? I haven’t been able to locate them on Warmoth’s site either (unless I’m missing something). I’m looking to use one in an upcoming neck build… any advice?
Gotoh not longer offers these via retail. They make them for Warmoth exclusively.
Great product, great explanation. I hope you guys never close down
just bought the replacement neck for my strat low cant wait
Why don't the Mooncaster necks have truss rods inside of them?
i thought that if you relax the truss rod, the string tension would make the neck concave, and if you tightened the truss rod,the neck becomes more staight. The string tension doesn't play a role ?
You are correct, and string tension definitely plays a role. I think the thing that is throwing you off is the fact that when a double truss rod is at rest, it is straight. Imagine a brand new neck. The truss rod is sitting in that neck, chilling, at rest, and straight. Then you put string tension on the neck, and the strings start pulling the headstock towards the body, and neck begins to bow. But.....the truss rod is still just sitting in there, relaxing, doing nothing. It is still, essentially, straight. It's made of steel, so of course it is providing some counter-force just by virtue of the fact that it is naturally more rigid than wood is...but it's still not actively doing anything. In order to provide the force necessary to counter the tension of the strings you have to tighten the rod. When you do this, the rod starts to bow in the opposite direction of the neck, exerting downward pressure at the headstock end, which pulls the neck back towards straight. To put it another way: the truss rod pulls the neck back towards straight by bending in the opposite direction. To be clear: this explanation *only* applies to double truss rods. Traditional single-style rods work differently.
Warmoth Guitar Thanks, that makes sense.
So how do you get the side adjustment box into the neck? It looks like just a solid piece of maple, no joins.
Usually, the fingerboard is a separate piece. If the neck is one solid piece, it won't have the side adjustment nut.
ua-cam.com/video/BDCuC6J4NFk/v-deo.html
I wonder if i can use it as a replacement for an American deluxe strat, I dunno if the offset screw (elite-deluxe models) is going to work well with the side Adjustment Mech!! Thanks #Warmoth Guitar Products
How do string gauges (increase or decrease) affect this?
Different string gauges will exert more or less force on the neck, depending on whether you are going up or down in size. That means you may need to tweak the truss rod a bit to get things exactly how you want them. Not necessarily, though. If it were me, I would play with the new gauge for a while and wait to observe any changes before jumping in and making adjustments.
Nice job, Aaron! Thanks!
So the side-adjustment nut is located outside of the neck pocket when having the neck bolted on, right? just making sure.
Yes. The point is you can make rod adjustments without having to mess with the strings. I've never had to use the major adjust at the heel with any of my many Warmoth necks.
Does the side bolt ever fall out?
