Used Keeley 4 Knob Compressor Effect Pedal

Used Keeley 4 Knob Compressor in great condition, delivering smooth, studio-style compression for guitar or bass with classic Keeley clarity and sustain. Simple 4-knob control layout lets you dial in Level, Sustain, Attack, and Clipping for everything from subtle leveling to punchy squish and added harmonic edge. Built in a rugged compact stompbox with standard 1/4" input/output and 9V DC power operation, it’s an easy upgrade for cleaner dynamics and bigger tone.
