||Wah mod for variable Q?|
Are the mods out there for this?
Do I want to do it?

If yours is the crybaby style wah, there is a resistor across the inductor. Varying the value of this resistor varies the Q (if i remember correctly)
You'll have to tell us what pedal you want to mod.

It's the GCB-95.
Sounds like it's just 4 more resistors & a 5 way rotary to me.

Another useful mod would be to vary center/resonant frequency. A variable capacitor (two parallel caps with one in series with a variable resistor) in place of the cap in the feedback loop between the emitter of Q2 and the base of Q1 would work nicely. Don't understand why anyone would prefer a rotary with presets and all those extra parts to a continuously variable pot.
One more thing; increasing the input cap (in the range of x2 to x5) of course would let more bass in.

Tried a few of the mods there & put it back.
Just wanted to give something a try. I really like my wah, just bored.
