'alut,
J'ai trouvé ce mod sur internet, c'est assez intéressant je trouve et je m'étonne de pas l'avoir trouvé sur des sites français comme Guitariste ou AF alors je vous en fait profiter en même temps que j'ai besoin de votre aide.
voici le mod (qui est en anglais):
This makes your Crybaby wah switch on when you put your foot on it, and turn off when you remove your foot!. It will also be equipped with true bypass. That means that the circuit is bypassed when the wah effect is off, instead of passing through it (that ruins your sound, makes distortion sound like a bad fart, etc)
If you might want to control your wah the original way for some reason, there's a miniswitch on the side that lets you choose between the two modes. When the wah is in foot-on-pedal mode, a green led lights up to indicate this. I also placed a red led that indicates that the wah is on AND in original mode. The thing a hate most about the standard crybaby is that you can't see if it's on or not, so thats why the red led is there.
step 1Buy parts:
You have to buy a few parts for this mod. I bought them all together for 10 euro's or something:
- 3PDT stomp switch, to replace the stock one
- green 3mm LED
- red 3mm LED
- 350 ohm resistor
- 390 ohm resistor
- 3PDT miniswitch
- DPDT mini momentary switch, with button.
- thin electrical wire
- superglue or two led holders Tools you (might) need
- plyers, for cutting the wires and tightening the nuts
- a wire stripper. You can use the plyers if you dont have one, but be careful not to cut the wire
- a drill and a set of drill bits
- soldering iron
- screwdriver
step 2Replacing the original switch:
Put the wah on its back and grab a screwdriver. Unscrew the four screws holding the baseplate. Now, cut the wires coming from the stomp switch. Cut them close to the lugs, we still need these wires! Now, remove the switch (use plyers to unscrew the nut). Put in the new switch, and test it by kicking down the pedal. Adjust the height with the nut and washers to get it working. You don't want to have to apply 10 tons of pressure on the wah to turn it on, but on the other hand, you don't want your wah to switch off when you just press the pedal down, right ?
step 3Drill holes for new components and fitting the leds:
Now, time to start drilling ! This is probably the hardest part. You have to drill through solid steel. Its pretty hard steel too. I strongly recommend a pillar drill for this, since it is more stable and powerful. Lets start with the biggest hole: the one for the momentary switch. It has to be drilled right through the top surface of the pedal. The best spot to drill is probably between the 'A' and the 'I' (there's AMPLIFIER on the left and INSTRUMENT on the right). Grab a drill bit (i think it was 5 or 6 mm, can't remember. Measure the 'shaft' of the switch to find out) and drill right through it. Yes, this takes a while, and you'll have to apply quite a lot of pressure, but you will get through in the end We're not going to place the momentary switch yet. You won't be able to wire it anymore if you do. Now the side of the pedal. We need 3 holes: 2 3mm holes for the leds, and a hole for the miniswitch. I drilled them next to the output and the DC in. Check out the picture below. Put the switch through the hole and screw on the nut. Now, lets fit the leds. Grab one, and just force it into the hole. You can also use special led holders, but I this is the lazy mans way (these holders require bigger holes!). Then put a small drop of superglue on the led and wah casing (at the inside!). Wait 2 minutes and your done, these leds won't be going anywhere.
step 4Wiring the thing:
Ok, soldering time. Use my wiring diagram. It should be clear from that. Don't worry, you will not destroy your wah if you mix up wires. IMPORTANT: - check out the drawings of the switches. There are a few important notes! - pull the wires for the momentary switch through the pot hole, and solder the switch outside the casing. This because you have to fit the momentary switch with the wiring already done to it, and it can't go through the pot hole (learned that the hard way) This step will keep you busy for a while believe me Tip: use different colored wires. It makes debugging a LOT easier, since you can see where the wires are coming from. After you wired everything, install the momentary switch. Be careful not to damage the wiring!

Your wiring schematic is wrong in terms of the momentary switch. Here is how it should go:
4 5 6 (looking at lugs with the common to left, normally closed to right.
1 2 3 and lugs numbered as shown)
C NO NC
1= Purple wire (Output to amp, to middle lug of middle row on 3pdt switch)
2= Blue wire (The effect loop return, goes to wah pot)
3= Green wire (Input from guitar, goes to the PCB harness)
4= Green wire (The effect loop input, goes to top right lug of the 3pdt switch)
5= Solder your jumper wire from 5 to 3)
6= No wire here
With this arrangement the switch (as long as it is the same type of momentary switch with the same C-NO-NC orientation as shown in the drawings in the instructable) should work as expected.
As drawn in the instructable the wiring diagram results in no signal with foot off (C-NC connected, which as drawn means the guitar input flows to the effect loop return). With the Foot On you get Clean (C-NO connected, the guitar input connects to the amp output). At least this is what I see...I had wired it as shown in the instructable, and posted stating that I had no signal foot off, and wah with foot on, but I may have been frustrated at the time and wrote the wrong thing...if you follow the signal paths, foot on should give you a clean signal as it is currently diagrammed.
Also, for other who know nothing about these switches, the lug are flat. To orient the 3PDT stomp switch and 3PDT mini toggle switch correctly for wiring as shown in the instructable, the lugs should look like this:
I I I ON _ _ _ ON
I I I for the stomp, but like this: _ _ _ for the mini switch.
I I I _ _ _
I think that is correct for all stomp switches. For the mini 3PDT toggle, you just need to make sure the "ON" throws are on the left and right as shown.
Sorry to be so verbose, but I am not an electronics hobbyist, so having this spelled out in the instructions would have saved me a lot of pain. No offense to the author...this is a cool project, and thanks for posting it!
step 5 TEST:
Lets do the first test!
Plug a guitar cable into the instrument input, and hook up a 9V power supply (battery or adapter, doesnt matter). The pedal is now powered. If the green led is on, flick the miniswitch. If you see no green led light up at all, check your green led. Its probably wired in reverse, so swap the leads and try again. If your green led works, press the momentary switch. The green led should not go off, if it does, you probably made a serious wiring mistake. If everything works, flick the switch and test the other mode:
- NO LEDS ON - The pedal is probably in the original switching mode. Stomp the pedal down. The red led should light up. If it doesn't light up, its probably wired in reverse. Swap the leads and try again. Also, try to push the stompswitch down with your finger. The switch might not actually switch because it's not mounted properly. Try raising it if this works.
- RED LED ON - The pedal is in the original switching mode. Stomp the pedal down. The red led should go off. If is doesn't, you've made a wiring mistake. Maybe you bypassed the switch somehow. Recheck the wires with the diagram. Also, try to push the stompswitch down with your finger. The switch might not actually switch because it's not mounted properly. Try raising it if this works.
If this all works fine, there is a big chance that the actual wah will work as well. Plug in a guitar and turn on your amp. Don't crack it up yet, it might squeal or buzz. THIS WILL NOT KILL YOUR AMP OR GUITAR, don't worry. Try the wah in both foot-on-pedal and standard mode. Possible problems you can face:
- buzz, and no guitar sounds. Solution: a wire is not connected. If it doesn't work in both modes, with wah on and off, it is one of the main wires coming from the circuit board, going to the miniswitch. If it doesn't work in one of the two modes, check out that mode for loose wires. If it only works when the wah is off, or only when the wah is on, check the wires on that side of the switch.
- squeal. solution: you mixed up the two wires from the wah circuit to the miniswitch. Just swap them and it should work fine. Again, if it only works in one mode, just check the faulty mode and those particular wires.
- nothing. Just silence. This means there is a shortcircuit somewhere. Check if there is any bare wire that hits another wire or lead. Also, check for mixed up wires. Again, try to isolate the problem by testing all modes.
Don't give up. Testing is always the hardest (and most boring) part. But eventually you will get it working![/img]
J'ai essayé ce mod et c'est plus compliqué qu'il ne le semblait. Disont plutot qu'il est imcomplet, par exemple où doit on souder le fil bleu qui part du PCB??
Par ailleurs, comme le dit une personne qui a laissé un commentaire à propos du schéma, celui-ci contient des erreurs, qu'il corrige dans son message mais en suivant ses conseils il me reste des fils que je ne sais pas où souder... bref c'est un peu le basars.
Est ce que quelqu'un qui s'y connait aurait la gentillesse de refaire le schéma exact en détaillant la position de chaque fil et l'orientation des switchs (pattes verticales ou horizontales).
je vous en serais très reconnaissant car ma wah est éventré, j'ai percé les trous mais je ne peut rien en faire d'autre pour l'instant.
merci à tous!
