Used Keeley 4 Knob Compressor Effect Pedal

Used Keeley 4 Knob Compressor in great condition, delivering the classic Keeley sustain and sparkle for guitar or bass.

Built in a rugged compact stompbox enclosure with standard 1/4" input/output and 9V DC power for easy pedalboard integration. Quiet, musical compression that enhances pick dynamics, adds sustain, and tightens your tone.
