Used Keeley 4 Knob Compressor Effect Pedal

Used Keeley 4 Knob Compressor in great condition, delivering the classic studio-style squeeze and sustain players love. Simple 4-control layout (Sustain, Level, Attack, Clipping) makes it easy to dial in anything from subtle leveling to punchy country snap. Standard 1/4" in/out and 9V DC operation (center-negative) fit seamlessly on most pedalboards, adding quiet, musical compression that enhances clarity, note bloom, and overall feel.
