Used Keeley 4 Knob Compressor Effect Pedal

Used Keeley 4 Knob Compressor Pedal in good condition, delivering classic studio-style compression for guitar and bass. Simple 4-knob control set (Sustain, Level, Attack, Clipping) makes it easy to add smooth sustain, punchy dynamics, and extra sparkle without squashing your tone. Built in a rugged compact stompbox enclosure with standard 1/4" input/output and 9V DC power for pedalboard-friendly operation. Great for clean tones, country snap, and tight rhythm work.
