CMATMods Deluxe Signa CompThe Deluxe Signa Comp (Compressor) has controls for Sustain, and Level. This 4 knob version adds Tone control and Attack control to give you even more control over YOUR TONE! 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
