Different versions were made, most used silicon transistors. These had a Tone switch added which lowered the volume. The sound from these was the so-called classic chainsaw buzz.

An earlier version - ultra rare- used Germanium Transistors. These did not have the tone circuit and therefore had a very loud output. The circuit lent itself to a natural gating making the unit rather quiet, even when playing the noise floor is quite low. The sound from these is very rich, fluid and thick. Creating classic fuzz/buzz and brass tones. The fuzz control when increased did not change the volume too much, this makes it good for a clean / fuzzy adjustment via the guitar volume output.


The FY-2 is well known for its raw, distinctive, gated fuzz. There are two knobs on the pedal:

  • "Volume" (controls overall level)
  • "Fuzz" (tone)
