I had a neon meate dream of a octafish. And an obsession with the Fuzz Factory circuit, and buying old AC128 transistors. The circuit is simple and easy to knock up, the enclosure and art concept takes longer.
I added a “bulbous” (fat) switch.
There’s a 100nF capacitor going from Q1 to Q2 (C2 in this schematic):
All the switch (SPST) does is switch in another cap (4.7uF) across that cap giving it lower frequencies.
Bulbous also tapered!
(Tin Teardrop would be a good name for a pedal. And Orange Claw Hammer for a compressor or Bat Chain Puller for a delay…or a Booglarizer?)
