fuzz-swell-wah

[Storing!]

My friend's a bassplayer that likes strange sounds for his bass. Among other things he's using an ampeg scrambler.
One of his toys is a Colorsound wah-fuzz-swell. He likes it a lot, but the fuzz isn't very usable because off a volume drop when engaged. I'm trying to fix this for him. For that a schematic would be really helpfull. My web search so far was unsuccessful.
Anybody out there who can give me a hand?

Thanks, E

The problem with most Colorsound pedals is that the circuits change alot overtime.
(They even admitt on their webpage that of 10 old tonbenders they analyzed for a reissue no  were alike).

I  have a relativly new fuzz - wah with twin t wah with only 1 transitor and a "fuzz" which is rather a Tubescreamer like overdrive.

I am afraid you need to trace the schematic yourself or at least provide photos (INSIDE!) to help to identify the version .

Here is the schematic






The fuzz is on the right.
To have a bigger output change the trimmer to 100k and the 100 ohm reistor near the second transistor to 470 ohm or even more
(I modded one and i used 1k2. very loud...)

Thanks

This will make the fix easier.

Could you please report if this schematic matches your pedal? Or if there are differneces?
