Boss HyperFuzz FZ-2 or Behringer Super Fuzz SF300 Mod

Mods for a more pleasing distortion without the "octave" effect and adding the volume control in the boost mode:
  • Remove Q13 and its circuit to get the octave effect out, as the picture shows, its possible to remove the 1k resistor initially to test this mod.
  • Replace the 10K in Q14 base for a 1K resistor, to increase the stomp volume.
  • Jump the part of the mode switch and cut one lead to add the volume control to the boost mode.

See the picture:
