Used Keeley 4 Knob Compressor Effect Pedal

Used Keeley 4 Knob Compressor pedal in great condition, delivering the classic studio-style squash and sustain guitarists love. Simple 4-control layout lets you dial in Level, Sustain, Attack, and Clipping for anything from subtle leveling to punchy country snap and singing leads. Built in a rugged, pedalboard-ready enclosure with standard 1/4" input/output and 9V DC power (center-negative) for easy integration into any rig.
