Very useful. I appreciate your process. A comment on wire gauge: the pipe analogy works. There is another factor. Higher frequencies tend to travel closer to the outer surface of the wire (physics). Therefore theoretically a larger diameter (gauge) of wire will have more surface area for the higher frequencies to use. Increasing relative surface area is one theory behind Litz wire often used for high end speaker or even instrument cables. Several strands each electrically insulated from the other, usually with varnish etc. in practice Litz wire tends to be made with a very thin wire with more strands thereby increasing the relative conductor surface area. So theory would say that thinner wire with more bobbin turns would yield a “flatter” frequency response. Tonal properties can be tailored using winding patterns. Not wanting to be one of those heckling nerds. As an armature luthier for my own projects I’m learning a ton from your videos. My knowledge and schooling is electrical/electronic engineering so please forgive. Interested in your thoughts on the above if you’re so inclined.
Fantastic video Chris! Thanks so much for this series. Looking forward to the others. Loved the demo of the magnet. Really great way to make the point, smart.
Just what I needed. I recently built my own winding machine, and have made a pair of low-wind pickups for my own guitar. It all went well, but now I need to have a deeper understanding. Thank you!
Incredibly informative videos, man. I've been watching your pickup series multiple times per vid, as I am getting ready to start winding my own pickups at home. Any advice for a pickup winding noob? I have guitar assembling, setup, finishing experience and have been a gear snob for 20 years or more. I am tired of spending 80 bucks a coil on good pickups and want to get to where I can make stuff that sounds good on my own--maybe even sell them down the line.
I've subscribed and will tell my friends. Killer info on your channel.
Subscribed - dude I’m modeling your format of doing this. Got the magnets ordered got the vise ordered and most of the stuff to get a pickup/humbucker built and tone-tuned(at least to play around with the tone tuning part)
Very cool, great presentation
Also when you put a volume pot and tone pot that is 250K pots in parallel with the guitar pickups LCR which changes the resonance peak Q peak of the pickup. The Resistance value of the pots will shift the resonant peak of the pickup even that its a resistor its changes the LCR of the pickup. Most people think only C&L can shift the Q point but resistance of the pots will shift the Q point. You should make a video lesson about this because 500k pots and 250K pots will shift the pickups LCR value
Really useful！！
Thank you！
Hi Chris. I cannot believe the wealth of knowledge you have on here, it's actually mine boggling. After watching a dozen or so of your videos I'm actually more confused than I was before. I bought a Tacoma Dreadnought about 20 years ago and it has almost totally delaminated on the sides. I I talked to a luthier nearby who would not take the job, so I decided to try and do it myself. My brother is going to help me and since he has always been good at everything he has tried, I trust him, and he does have a lot of painting equipment because he paints airplanes. I was wondering if you could recommend a specific strategy for us to attempt to refinish the sides of this gorgeous cherry burst. You have presented so many different products and ways to refinish it. At first I thought I would use the rub on type, but now that he told me he has all the spraying equipment I thought that might be the best (since the luthier told me today that the only way to get that effect that is on the side of the guitar is by spraying.).I also realize that matching the colors could present a challenge. I looked on the crystalac website and thought I would try the colored gel polish followed by the glossy instrument finish but I don't know if that can be sprayed. I tried looking for your website but I didn't see what I was looking for. Any words of wisdom would be sincerely appreciated. Thanks. Julie
My channel is really geared toward building brand new guitars from scratch. Refinishing old guitars is a whole different animal and not one I feel comfortable offering advice on.
Great channel.
You are on fire with these pickup videos. So resistance + magnet = pickup tone. Anything else I have to worry about for pickup tone?
Inductance + magnet composition + magnetic gauss = tone
Love this page. Do you have a clip that explains the tonal difference between magnetic pole pieces vs bar magnets? Also, the count of turns and wire gauge determines the magnetic field, but what if you used a really heavy gauge--say 22, and only had half as many turns? Of course, this is a theoretical question. Thank you!! Going to purchase your winding machine plans.
I'll be winding some single-coil pickups later this year and when I do, I'll shoot a few videos with one comparing them to bar magnets. An example of 22 awg wire according to www.jdguitarworks.com/coil/coil.html
to get the 7k of resistance with 44 awg wire on a PAF bobbin would require about 6k turns. Jump to 24 awg wire at 3.5k of resistance would require about 12k of turns. That's not possible. Going thicker requires more turns not less to get even half the resistance of a thinner wire.
@@HighlineGuitars Ah. I had it backwards. Thanks for the reply. Looking forward to the magnet reference video.
Chris, I just ordered your pickup winder plans from www.eguitarplans.com. Fantastic!! The drawings and cut list are fantastic and easy to understand. This is the best of four different winders you created. Your plans make building an amazing pickup winder for a fraction of what lesser winders cost. Thank you so much. Any of you who want to build pickups, you should download and build this winder!
Thanks DALG Guitars, that was the nicest compliment I've had in a while.
I'd really appreciate that link to the online calculator, but I notice it only seems to accommodate AWG and imperial dimensions. Is there a version for SWG or IEC and metric measurements?
Not that I am aware of.
Is there a "rule of thumb" for making a set of pickups to make them balanced? Like if you know you want 8000 Ohm for the bridge, what % do you increase/decrease that number by to balance the neck?
There is no "rule of thumb" that I am aware of, but for a neck pickup, I shoot for about 78% of the bridge pickup.
How did you determine the relative tightness of your winding machine?
Trial and error. I wound a coil with a number of turns based on the 78.5% fill factor and compared my actual resistance to the estimate. The actual resistance was too high so I went with the recommendation for 72%. Of course, a lot depends on the amount of tension you put on the wire.
"Watch what happens when I install the magnet into the pickup..." WHAT!!? I thought you were about to rock my world there for a second, there's no way the magnet changes the DC resistance, right!?! Oh, right, yeah, no change.
I am having trouble with the website you use in this video lately, sometimes for the same specs it gives you different results of the winds, is there anorher source like this?
I don’t know. I have never had a problem with it, so I’ve never looked for another one. To get an accurate number is very difficult because the math is extremely complicated. This site probably simplifies the calculations to get you into the ballpark.
@@HighlineGuitars Lately I've been using the mobile phone, and sometimes the website goes crazy. Maybe it's a problem with the website working on a Phone
@@juanilloJMTV Who knows. It works fine on my phone and my iPad.
When do you put in the Kyber crystals?
Just before the wax potting. Makes sure it isn't jangling about in there
@@scguitars - And then when is the Turbo Encabulator installed?
What
A 24 volt relay coil and magnet
Not on topic, but what is the microphone clipped to your shirt?
Rode Wireless Go. My 4th wireless mic.
@@HighlineGuitars Thanks! Is the sound quality improvement with a wireless worth the bother? I am happy with the built-in microphone sound on my Panasonic point and shoot camera. But my shop is small and quiet most of the time...
I recently was informed that even the thickness of the insulation which dictates wire separation distance makes a difference...
I explain that in this video: ua-cam.com/video/FajyKH_vJ_8/v-deo.html
@@HighlineGuitars Hi ! Thank you.. I will have to study all your valued work.. Thank you..
Why don't people just make taller bobbins so they can use thicker wire for any given number of turns, or keep more of the coil a more optimal distance from the pole pieces?
They do. However, you can't just buy taller bobbins (no demand), so you have to 3D print them yourself.
Hey that is not a humbucker on that shirt!
