Pedal Mods: CryBaby True Bypass and LED Indicator
Вставка
- Опубліковано 21 жов 2012
- A common mod for a CryBaby wah wah pedal is to install a true bypass switch and LED on indicator.
The true bypass allows the signal to bypass the pedals circuitry when not switched on, meaning that tone won't be lost while the pedal is off. Wah pedals have an input buffer which the signal runs through, even while the pedal is off and this can take away both gain and tone from the signal.
What I found after doing this mod was that there was a noticeable difference in the volume while off, and that the overall tone was better, although not by any massive amount.
The sound comparison at the end shows how similar the before and after cases are, although the more gain in the after case is apparent. Once again, the difference in the room sounds more obvious than the recorded samples. - Навчання та стиль
I followed your instructions and my pedal now is working true bypass with led.
Thanks, dude. Greetings from Brasil.

thank you sir, this tutorial is by far the best and easiest to follow here on youtube. just wired mine up for true bypass, LED's are on the way so that will be next,. Maybe it's psychosomatic but I noticed with the true bypass mode that the sweep range of the wah has improved drastically, even if it is all in my head.
Great instruction! 4 years ago I was inspired by this and unsoldered my crybaby. Finally I had the courage to finish the job, everything works Excellent! Thank!
Your channel has come a long way. I did this mod and love it. Thank you for keeping this video up. I need to fix a couple of wires and forgot the wire layout. Surprised the vid only has 140,862 views. It's a great mod. Thanks again.
First soldering project since I was a small boy. Now I have a Crybaby with true bypass and LED indicator. Many thanks for your video!
This is by far, the best Mod Video I have ever watched. Awesome detail, discussion and direction. Hope you do more pedal mods real soon!
Thanks for the step by step and the info... I made the mods to my Dunlop Crybaby and they work perfect... no more guessing if my wah is on! And the true bypass is awesome!!!
Very clear and easy to follow. Thank you for your knowledge and passion, it is appreciated.
Awesome instructions. I just did this mod and it worked perfectly. Thanks for posting.
Did my 2nd one of these tonight! Used a blue LED and it looks great! The Wah only cost me £10 and I already had the parts in for the upgrade so a bargain! This video is the best :)
Wow, awesome video. Did the project and it worked great. You did an EXCELLENT job at explaining things, and showed it all very well. Thank you!!!
followed your instructions 100% and the mod works great! I mostly did this to install the LED but the true bypass is cool too. thanks so much Colin!!!
I followed the instructions and my pedal worked on the first try!
Thanks!
hey man,
Thanks so much for posting this. You made this mod beyond easy and i also added the vocalizing mod and volume mod. My effects chain is louder, and so much clearer. You are a champion!
Cheers again!
keep making videos, yours are always interesting and fun and deserve more recognition :)
Thank you so much for your vid and your perfect explanations , I did the mod , it works perfectely.
Just a thing , when you wire the leg of the 10n capacitor , you don't have to cut the trace on the PCB .
In any case , great job ! Cheers.
I did this mod and now my pedal is a radio lmao.
Jacob Kantor excellent !
Same
OMFG ME TOO I HATE IT I JUST WANT THE DAMN LED LOL
Hey thanks man. WIth your help, I just finished the mod. Thinking about adding switchable inductors next.
Hello yeah!!!! It worked!!!! Thanks little buddy from across the world. You rock. I watch all your videos.
Thanks for the tutorial, i followed it and it surprisingly worked first time which i was not expecting. The only thing i would suggest would be a higher value resistor for the led as mine is blinding when on.
Did this recently as my first "serious" mod. Very easy to do and everything worked first try! Desoldering the leg at 6:20 is unnecessary as you broke the trace, you can just solder that wire to the back for a better connection. Also very glad I paid attention to the voiceover around 12 minutes and not just the schematic with the mixed up colors as you said! I put a purple LED on the left side and it looks sick.
Thanks dude
Gonna give it go...love the pedal but it really does change the overall tone when disengaged.
This mod sounds like it changes the wah sound slightly but I could live with that no problem.
Thanks again
Hi there. Just wanted to say thanks for sharing this information. I followed your instructions and it worked first time! A great improvement. Thanks again!
I just tried this on my Zakk Wylde WAH ZW-45. Let me tell you sit sounds way better in my chain and the LED looks awesome! Thanks for the great tutorial!
That works so fantastic! Thank u very much, great sound and the light is on.....
Awesome! I really love my Crybaby 95q with the auto wah because I know it's gonna kick on and off when I need it to. I'm gonna have to try this on my Vox that it replaced on my pedal board.
dude love ur videos. i thought i was the only person with that backwards clock
Great video very clear, liked the drawings
Took about 30 mins or so and cost about £2.30
£2 for switch 30p for led and 6p for resistor happy days
Bought the other bits for the other mod that u did so will do that a bit later
Thanks
I put my wah thru a boss line selector that seemed to take care of my tone/ true by pass issue as well since it's run thru an effects loop also put an LED mod on mine after seeing this video thanks Colleen for the inspiraton
Thanks for this tutorial man! Works fine for me! You are the man!
Oh MAN! I just came by this looking to mod mine. I'm subscribed and have been watching for a couple of years -- you're just a wee babe >_< (p.s. thanks for being so informative and such a legend!)
Just done this, took about 40 minutes start to finish and worked first time. My LED is a little bright (maybe needed a different resistor?) but it's much better knowing if the thing is on or not.. I'm a novice to this kinda stuff as well. Thanks for the vid, dude! Each step is very clear and educational. Might look at the more wah mods video next...
A resistor of a larger value will make the LED dimmer.
It's there to resist the flow of electricity to the LED, so the more it resists the less light you get.
Glad to hear that it worked out well.
Can't understand a word he's saying but a well made and very informative video. Well done.
Worked perfectly. No annoying sounds from the switch even when it's a cheap one ($3 USD on Chile). Thank u buddy. Used a high luminosity blue led and a 1k resistor / multistrand wires.
Thanks so much for this video. Worked great!
MUCHISIMAS GRACIAS DESDE ARGENTINA!!! El unico tutorial que esta bien explicado el unico que me resulto, en 20 min listo para funcionar!!! un maestro!!!
Hi there. Just wanted to say thanks for sharing this information. I followed your instructions and it worked first time! A great improvement. Thanks again! [2]
I did mods in "Pedal Mods: More Wah Mods" video too. Now my Cry Baby is other!
Great vid. I may try this to my old Cry Baby since I have all the parts.
After I finished this mod, I plugged in my guitar and amp and it didn't work...I guess in my excitement I forgot to plug in power for the wah pedal. Once I corrected that, I heard a big difference right away in the lack of tone suck and volume drop. Because of those initial reasons, my Crybaby has been kept off my board. Now it is going back on. Thanks for the video guide.
Thanks for the awesome and clear wah mod will have to give it a try
Thanks for the video. Just bought an old CryBaby for a decent price, but I immediately found out how much tone this thing sucks. According to the specs, the input impedance should be 1M Ohms, but if I reference the tone suck with Boss NS-2 (1M input impedance), the difference is a night and a day.
thanks for this! I successfully modded my pedal using your video :)
For sure! I'm not experienced with wiring diagrams for 3P3T switches but they offer many possibilities. Just wire two LEDs to the same resistor, but if you like, you can connect the other LED to other poles on the switch. Adding a second LED to the resistor (parallel) will add your Ma, as opposed to adding your voltages which leave less for the board and requires another resistor. You may want to research the wattage of the resistor to make sure it can handle it but it's not very hard.
Hi! Your instructional is very clear and straight forward especially the quality of your video. I followed your instructional and did my crybaby to work but the LED does not work for some reason. I use 1k-ohm resistor(1/2 watt / 5%) and 5mm LED(16mW min / 1.2v / 100ma / 45' 940nm) from radio shack. All of connections are double checked, everything is clean.
Super video m8, and mod worked like a charm :D Sure wish I would have known what the h* I was doing, but as long as it works ;) Now im gonna check out your other Wah mods!
This mod will work for most common wahs, the only real problem I can think of is if the components I've mentioned are located in different places, or in the case of the 535Q, the foot switch is attached to its own PCB and connected to the main board by ribbon cable.
In each case carefully trace where everything is going and you should be ok.
got the regular led, it works perfect! thanks a bunch!
I modded my wah thanks to your video thanks a lot :)
thanks for this very clear instructions & demo, great job! i might try this.
though, i've seen a lot of people putting the LED on top face, any reason why i shouldn't put it on a side?
my wah is normally first in line so for me visibility is better when the LED is on the left side (somewhere in front of the output) i think
Thanks so much for putting this video out, I never realized how much tone the wah sucked. I'm definitely going to change it to true bypass and add a light to the pedal to make my wah pedal better for my channel. Thanks again, this video is super easy to follow and really informative. Also how can you tell which resistors are which, because I want to add LED lights to another pedal I have.
don't listen to much of a difference after modded , still is admirable the work and the knowledge you have to do something like this.
Very helpful especially that android app that u mentioned. Keep up the good work man
It would certainly be possible to change the cheap box style caps for an equivalent.
I'm thinking about doing so myself pretty soon, along with winding a custom inductor to replace the stock one. I suspect that changing the cap for a higher quality one that is of a different physical construction will change the sweeps smoothness and richness, in the same way different caps on a tone control do.
Naturally I'll have a video of it up when I get round to doing it.
Just did the LED mod, thx, peace of cake!
This man is a legend
I found it wasn't a straight swap. Even without any washers, the 3-pole switch was too short. So I also replaced the felt under the treadle. It was worn almost right through. I used a dremel polishing wheel. Its thickness easily made up for the difference. Thanks for your video!
Thank you for your Video. Very easy to follow and informative. I noticed you connected the resistor to the cathode side of the LED mot other video indicate it should go to the anode. Does this make a difference?
i prefer the sound before bypass !
It works but I ended up with a lower output wah that sounds like a telephone (no bass and attenuated high-end). I checked everything - I've done it right. Even did the stinkfoot tweak to get rid of the pop when activated. Also tried to change those input gain resistors - no effect at all. Any suggestions? The wah really sounds terrible now :-(. I had a different input cap in the original circuit - one with a plastic "case".
I follow instructions closely,and I wish there wasn't a long pause between "I cut myself" and "two new lengths of wire"
Hey man great tutorial, love your stuff!
Just a small question, do I have to remove the capacitor and resistor from the PCB board for the LED or can I just solder the wires on the board like you did with them still connected to the board (couldn't quite see it right on the video)
Also the capacitor for the truebypass stays disconnected from the PCB board after hooking up the wire for the 3PDT switch right?
Thanks a million dude, you're the best!
Thanks for the tutorial!
A couple tips for people thinking about doing this:
-You don't need to scratch out the trace on the circuit board if you are pulling out one end of the capacitor, it's redundant.
-The new boards have a different type of capacitor that is surface mounted to the board, so there is no room to pull out one end and solder. In that case, you SHOULD scratch out the trace noted in the video, and just solder the wire directly to the board where the capacitor connects.
Thanks so much for making this vid! I might attempt this with my crybaby.
Although the wah switched off tone is clearly better after the mod, it sounds to me like the wah switched on is better before the mid?
I am definately going to do this because I think it's simple enough for me to do without messing up. I hope :-)
this is a cool video i'll defiantly use it as i'm getting a dunlop wah in a few weeks. on a similar note do you think i could mod the circuit board of the pedal too become the jimi hendrix signature version seeing as the original is like £40 cheaper
thanks a lot, i did the mod, but my PCB was a little different from yours, my capacitor was like a blue box, but still your video was very useful!
Great video! Just did it and worked great! Thanks :-)
Agree with everyone perfect tutorial thanks
Im trying this as a first project in stomp box modding.You say you are using a 500Ω resistor on a 5mm red LED.Typical values for that type of led i find on the net are 1,8-2,2V and 20mA.With those numbers though, the app says i need a 360Ω resistor.
Are you just going higher to be on the safe side, or are your led values different?
I actually bought a bunch of color leds, and each color seems to need a slightly different resistor value (ranging between 270-360Ω).Should I go for the exact value the app gives me or would it be easier/better to go for something that covers all, say 400Ω (or 500Ω as you did).
Anyways, loving all the vids man, that accent makes them even that much better (Greek guy here!)
The Shite Paul is still around. I'll hopefully have a new episode of it quite soon :)
Dude, cool video. I just really want to hear you say... "But we haven't had second breakfast." Thanks for the info!
Awesome vid, thanks! Can you tell me what the value of the capacitor is that you first unsoldered? Mine disintegrated when I moved it! My pedal is over 20yrs old so not unsurprising! Thanks! Is it .22uf? This is my first project and I haven't touched electronics in about 20 yrs so I'm relearning everything.
I have a series of 3 videos that look at wah modifications, the other 2 focus on changes to the wah sound by firstly altering resistors on the board and secondly by replacing the inductor.
Check out my channel for more.
Fantastic video...how calming the Scottish voice is....
I know this video is 1000 years old but damn!! You’re great at this! How did you learn this stuff? The internet?
Awesome tutorial... but i dont get it why is necessary to desold one leg of the capacitor and pull it out ? The Why the wire shouldnt be soldered on the bottom of the PCB directly to the pin of that Cap leg, like you did for the LED. The connection from the input jack to Cap is already cuted so...?
That's my first thought. Why cut the connection when you're just going to desolder the capacitor and leave it hanging off the board anyway? And it seems a little insecure only connected to the board at one point. I think what he was supposed to do after severing the connection was just solder the white wire directly to the back of the board where the capacitor comes through.
Hi, I just wanted to ask before I do a true bypass mode on my wah
what's the difference if you do not cut the buffer?
like the one on this vid? > Wah Mods (Part 1): True Bypass
Thanks
Hi.
Do you know how I can take apart the two pieces on the wah?
Excellent thank you! Does anyone know this sequence for a Rev C board? I can't seem to find anywhere.
Hey man, great video. What switch do you replace the Carling spdt with? The Carling dpdt has only 6 connections.
I would love to mod my cry baby into wah and volume pedal. Can u do a tut on this?
Hey, I have (i think) an early 90's crybaby, the circuit board is a GCB-25e, i'm clueless about where i need to cut and where to solder, any help would be appreciated. thanks
Your little blue box is a capacitor, so don't worry about that.
You'll still want to break the connection between the two components.
With the green wire, you will want to connect it to the top left contact, and then add a small length of wire that bridges the top left contact and the middle contact on the bottom row. This is referred to as a 'jump' wire, so that's why I said it jumps to the bottom middle. Sorry for the confusion.
Thank you for the mod tutorial. just did mine today and its working very well.
Very good video aswell
Well I've looked through about all of the comments and NO ONE I saw has asked about the Dunlop Crybaby Q95 switchless model????? I have this one and want to know if and how you do this mod to it?? When I used this pedal with my Marshall Valvestate it seemed to be turned off and in a kind of bypass mode, but with my Orange all tube amp it's totally evident that the effect is still being sent even when the pedal is all the way up with it supposedly ingaged in the off position. Is there a way to correct this?? I sure hope so for I purchased the Q95 for the reason of no swtch on off just put your foot on the thing and go! But there is way too much effect coming through the Orange amp when the pedal is in the "off" position. Please help or do a video on the Q95 crybaby for I'm sure there are a few owners that would like to know the same thing! Thanks, and excellent video I just wish it applied to my crybaby! :(
I did do the mod where you take the little tab loose and swing it out of the way and you can move the roller gear all the way forward more toward an "off" position, I haven't plugged it in to see if it helped or worked at all, I'll keep you posted, again this is for the crybaby Q95 switchless wah.
+Brad Ivie Well that trick doesn't work for the Q95! It renders the pedal useless, for you still have the effect coming through in the off position but when you try to activate the wah and step on it it does absolutely nothing!! SO I sure hope I can find the spot as close to where it was to put it back so that it at least works again lol! Someone please help!!?? How or can you make the Dunlop crybaby Q95 have true bypass?? Tell me you can...please.
Muchas gracias y salud desde Croacia
Great lesson. I have my switch for the LED and true-bypass, but I can't work out which way the switch goes, as in, I'm confused about which wires to solder to the correct pins. There's no pin numbers on the switch and wondered if this is a common problem. Plus, I ordered the wrong resistors; I brought 5 band instead of 4 band. All the values are correct, so can I still used them? Lovin the mods! I have seen others on the net and want to gather a list of possible mods, like controlling the Q with a knob on the side. Thanks!
***** Man, you are such a nice person to take the time to answer my questions! Thank you! I have ordered new parts for the wah and will attempt to do it again (messed it up the first try). Cheers :-)
Thanks Man....it's helpful
I followed the instructions, and when I turn the wah on no sounds come out, what should I do to fix this? (I ignored the LED and connected the cable straight to the switch, but I don't assume that's the problem)
That said, it is quite possible that you could design a circuit that would disable the battery when in true bypass, but for a pedal that wasn't initially designed to feature true bypass, it isn't very likely that feature will be supported.
Thanks for the great information. What inductor would you recommend to put in an Original Crybaby?______ Anyone?______
Hey brother I’m curious if you could do a video on how to do the true bypass mod on the crybaby bass wah. I have the mini and it’s killing my bass tone.
I doubt it was "killing your tone" nearly as much as you think. Colin said this was a tone sucker when off but it sounds WORSE after true bypass. That is what, sucked all of his tone. Smdh. I would NEVER do this. Why mod your pedal to lose tone when bypassed? Doesn't make sense.
Hey dude, where did you get the 3PDT switch from? I recently replaced my Crybaby's switch was a Maplin one (original was gubbed) and I cannot get the height right at all - if I move the switch up a bit, I turn it off while playing. Lower it by a bawhair and I can't turn the bugger on or off. I'm starting to wonder if the physical distance this switch needs to move is too much for use in a crybaby so a recommendation from yourself for a suitable one would be great. Cheers
+Richard Keel I purchased a whole bunch of them off of eBay, since I planned on doing lots of mods.
I had to play about with the number of washers to get the height correct.
Maplin are pretty dire for their choice of switches.
Hey mate...quick question...I was getting into doing the mod but found what looks to be a resistor instead of a capacitor where you solder the wire directly to the end? (1st board modification) Mine is an early 90's wah would it still be the same?
Has anyone figured out how to fix the "pop"? I did this mod step by step and the pedal is now somewhat useless with the on/off noise. I've tried various solutions of adding resistors at various points and nothing works.
Isn't possible to use the battery positive and negative wires to wire the LED instead of soldering wires to the pcb? (then I will only use the power supply of course..) Thank you!
Great video. What is the namm of the capacitor i talk about 4:40. I broke mine and need a new one.
I've done this mod a few times and it's always gone quickly and worked out great but just today while doing another one I ran into a problem I can't figure out. My LED isn't lighting at all. The pedal still works, I've tried 3 different LED's, a few different 1k resistors and all my connections have been double and triple checked but I can't get it to light up. Like I said I've never had this issue before any chance you know what could be happening and how to fix it????
Um, the schematic for the crybaby wah I'm looking at shows true bypass already. . . it shows switch one swaps both ends of the circuit out of the wah path down a single wire. I guess I'll investigate while I install my LED.
