Boss TW-1 T Wah turned to Fuzz
« on: April 27, 2018, 12:45:33 PM »
Hello,
I got an old Boss TW-1 auto wah from a friend. It was broken, giving only a high pitched squeal instead of a wah/filter sound.
I changed the caps in case there was something wrong with them. Now I get a fuzzy sound (even with the pedal on bypass mode.
Any ideas how I can possibly fix it? Schematic attached.
Thanks in advance

Any chance you could post the voltages of ICs and transistors etc?

Also, have you tried following the signal with an audio probe? Perhaps find when the fuzz is introduced?
To the extreme, I rock a mic like a vandal.

I will try to follow the signal and see if that gives me any clue. Thank you!
