Easily one of the finest compressors out there. Extremely transparent. Sports a blend knob which lets you retain original attack and tone. UNGODLY sustain on tap. Grit knob for adding dirt. Treble knob is subtle and works great for fine tuning the tone. True bypass. Like new condition. Comes with 15V adapter, but can accept anywhere from 9V to 18V DC. The more voltage, the higher the headroom. Velcro on the back can be removed cleanly. $110 shipped in the US, a bit more shipped abroad. Paypal, MO or check.
