Used Keeley 4 Knob Compressor Effect Pedal

Used Keeley 4 Knob Compressor in great condition, delivering the classic studio-style squeeze guitarists love. Controls include Sustain, Level, Attack, and Clipping for everything from subtle leveling to rich, punchy sustain. Built in a rugged compact stompbox enclosure with true bypass switching for clean tone when disengaged, it runs on standard 9V DC pedal power (center-negative) and fits easily on any pedalboard. A go-to compressor for country snap, funk clarity, and lead sustain.
