Wah Mods (Part 1): True Bypass

ATTENTION, PLEASE READ!!

If attempting this mod, then please go to the link at the end of this paragraph after completing what I've shown you in this video.

Upon completing the instructions in this video, the final step in order to complete the true bypass mod is to switch the black 'clean input wire' with the green 'FX input wire' on the switch. And then finally you have to break the connection between the new black 'clean input wire' and the jack input terminal using a craft knife to scrape away the copper connection on the PCB; which is illustrated in the link above. You will be needing a long bush dpdt switch for this mod as well

The GCB-95 pedal, along with a lot of other Jim Dunlop Crybaby wah pedals are not true bypass, and therefore effecting the tone of your instrument when the effect is turned off. This is called tonesucking, and the effect is that you lose some of the treble in your signal and lose a bit of gain as well. This is due to the fact that there is a stock SPDT switch and only allows one input into the unit that then has to run through the circuitry sapping your tone as it goes.

my pedal without any mods is hard as hell to turn on. I know its because of the stomp switch thing. So im wondering how to change the level of it without the mods.

[Cappi666]

There are screws that mount the switch to the body of the pedal. The lower the screws are down the shaft of the switch, the higher the switch will be under the contact of the moving pedal part; which should make it easier or far too easy to turn on (depending on how much you've adjusted it).

Hi! Great video. But since i've made this mods, i have a problem : when I switch on and and switch off the pedal, the switch makes a noise ("ploc"). Is it because of a bad switch (it is brand new!)? Is it because it is a true bypass now?

Thanks

Did you make the cut in the PCB; as in the description, which I forgot to add? If so, did you switch the 2 wires round on the switch as well?

Where did you get your switch from? And is it made my Carling?

It irritates me that Dunlop don't just do this anyway when making the pedals!

Why is there no LED?!?

It's a bit silly!

Thanks for the mod, worked great (even with my crap soldering skills!).

i can do this with my 535q crybaby right?by the way i admire how clean your wah is...i need to work on that lol

[timrocket2]

ATTENTION!! IF U ONLY DO STEPS IN THIS VIDEO U WILL NOT HAVE TRUE BYPASS!! as stated in description there are more steps. i just succesfully put true bypass in gcb95f and to complete u must cut a connection in the circut board (PCB) or what i did take out the 6 buffer components. also have to add a ground wire to PCB next to input or ground to pedal. just trying to help. this video helped me out a lot cuz i never soldered but there is steps migging. i found em on the web pretty easy.

[kramerfrank5150]

can i do this mod if i do the led ight mod that you posted???

thanks

I thought you where giving us a tutorial and now that I've finished and read the comments and then seen your description I now realise you are the dungeon master with a riddle at the end!

why don't you just make a Wah Mods (Part 1.5): True Bypass? so us simpletons know what it is you're trying to explain in your description?

[urworstnightmare22]

@EarlMendoza03 You shouldn't need to. It SHOULD be true bypass. Take the battery and adapter out and engage the pedal. If you still hear the signal its true bypass

[GuitarBoyA7X]

does this work on vox v845 model?

[EarlMendoza03]

hi.can we do this mod on a CAE crybaby?

[SRVRHCP]

Does this mod work on Vox v845 models? :)
