I beleive that Electro Harminix makes a pedal that makes sounds like that called the micro synth or graphic fuzz or mabey the tube zipper. I can't remember which.
How's that speaker holding up? LOL I am sure those are the tonal accidents that created FX in the 60s. Very cool. I used to get distortion by pegging the levels on my cassette deck. This was before my mom would let me get an amp. Somewhere I have a tape of it....
