Following a "guts I would like to see" request, and a stroke of good bidding luck, here it is... the Dunlop GCB-95O Octave Fuzz Wah.

Now... could someone please draw up a schematic. I'm pooped!! :lol:

Not a bad pedal. Not an "in your face" octave, but a really nice fuzz. The wah sweep is nice and vocally (is that a word?). Video coming soon.
No matter how many times I cut it, it`s STILL too short!
