Used Keeley 4 Knob Compressor Effect Pedal

Used Keeley 4 Knob Compressor in good condition, delivering classic studio-style compression for guitar and bass with smooth sustain and punchy attack. Simple 4-control layout (Sustain, Level, Attack, Clipping) makes it easy to dial in everything from subtle leveling to squashed country snap. Built in a rugged stompbox enclosure with standard 1/4" input/output and 9V DC power for pedalboard-ready operation. A proven tone enhancer for clean and driven rigs alike.
