    Turning a Cry Baby into a true bypass pedal is a very simple mod.
    It's explained in detail on Fulltone's site.

    Thanks Jazz Ad. I don't see any bass wah's on fulltone's site, though, and the ones they seem to offer now are the kind where they're activated by putting your foot on the pedal....are you sure those can be modified (some conflicting info in other threads).

  5. Awesome! I'm going to do the vocal mod :cool:

    EDIT - Wait, that's for the GBC-95 or whatever the guitar one is, will it work for bass?

    My guitarist gave me the GBC-95 when he bought a new RMC
    :p

    I'm going to do the vocal mod by adding a pot in series, I'll have a knob sticking out the side but it should be worth it. I'll know by the end of the week.

    As for working on a bass version it seems they are almost the same thing based on this part of the article.


    Lower range: The 0.01uF cap controls the frequency range. A lower value shifts the wah higher in frequency, while a higher value lowers it. To shift the wah downwards (using more of the woofy bassy wah sounds), try a 0.022uF cap here. If you come across a bass wah cheap, buy it - you only need to change this cap to turn it into a guitar wah (or the other way around)! The standard bass wah uses a 0.068uF cap in this position. (Thanks to Matt Parlane for providing the bass wah value.)
