Used Keeley 4 Knob Compressor Effect Pedal

Used Keeley 4 Knob Compressor in great condition—an industry-standard stompbox for smooth sustain, tighter dynamics, and added sparkle. Simple 4-control layout (Sustain, Level, Attack, Clipping) makes dialing in subtle compression or squashed country snap fast and easy. Runs on standard 9V DC (center-negative) and fits any pedalboard-friendly compact enclosure. A reliable choice for guitarists who want studio-style compression on stage or in the studio.
