Used Keeley 4 Knob Compressor Effect Pedal

Used Keeley 4 Knob Compressor in good condition, delivering the classic Keeley squeeze with smooth sustain, enhanced clarity, and quiet operation for guitar or bass. Simple 4-knob control layout (Sustain, Level, Attack, Clipping) makes it easy to dial in anything from subtle leveling to punchy country snap. Standard 1/4" input/output, 9V DC power (center-negative), and rugged stompbox construction make it a reliable addition to any pedalboard.
