Used Keeley 4 Knob Compressor Effect Pedal

Used Keeley 4 Knob Compressor in great condition, delivering the classic studio-style sustain and punch players love. Simple 4-control layout lets you dial in Compression, Sustain, Level, and Clipping for everything from subtle leveling to squashed country snap. Designed for standard 1/4" in/out and 9V DC pedalboard power, it’s a quiet, musical always-on tone shaper that enhances dynamics, adds sparkle, and keeps your signal consistent on stage or in the studio.
