Used Keeley 4 Knob Compressor Effect Pedal

Used Keeley 4 Knob Compressor in great condition—an industry-standard compressor pedal that adds smooth sustain, tighter dynamics, and studio-style polish to any rig. Simple 4-control layout (Sustain, Level, Attack, Clipping) makes it easy to dial in anything from subtle leveling to country snap and singing lead sustain. Designed for guitar and bass, with rugged stompbox construction and true-bypass switching for a clean, transparent signal path when off.
