Used Keeley 4 Knob Compressor Effect Pedal

Used Keeley 4 Knob Compressor in great condition, delivering classic studio-style compression for guitar and bass with exceptional sustain and clarity. Simple four-control layout (Sustain, Level, Attack, Clipping) makes it easy to dial in anything from subtle smoothing to punchy, country snap. Built in a rugged compact enclosure, it runs on standard 9V DC center-negative power and features true-bypass switching for a pure, unaffected tone when off.
