CMATmods Signa CompThe Signa Comp (Compressor) has controls for Sustain, and Level. Footprint of a Boss or Ibanez and has a bright blue LED and True Bypass. I came up with this Compressor and I think it has a really nice wide range of application. It is very smooth with a lot of sustain and pop. Great low end. This can do Rock, Jazz, Country, Nashville, well you get the idea, not your standard Ross clone!. I use matched transistors, and it is true Bypass. Pedal is quiet
