Used Keeley 4 Knob Compressor Effect Pedal

Used Keeley 4 Knob Compressor pedal in good condition, delivering the classic Keeley sustain and smooth leveling that tightens cleans and adds punch to leads. Simple 4-control layout (Level, Sustain, Attack, Clipping) makes it easy to dial in anything from subtle compression to squashed country snap. Compact stompbox format with standard 1/4" input/output and 9V DC power for easy pedalboard integration.
