Compressor Boss cs-3 or Behringer cs-100 mod

 

 Bypass buffer mod (for more transparent bypass):

  • Input capacitor 22nF to 47nF.
  • Output capacitor 1uF to 10uF.
  • C15 47nF to 1uF.





*Use Boss schematic above to mod this Behringer stomp box.

  1. Hello,

    I tried this mod to behringer cs-100, but it has different pcb. Schematic doesn't match. Input & output capacitor values match, but C17 -> C1 and C2 -> C7. I was unable to find C15, it seems that this doesn't have Q4 at all. Now i can turn up sustain to max, there is no noise any more, but also it doesn't do much.

  2. Hi, how r u ?
    The schematic are for boss, the behringer copy then, Just localize the input and output jacks, and follow the circuit with a multimeter (continuity meter or resistance meter). Thank you.
