Used Keeley 4 Knob Compressor Effect Pedal

Used Keeley 4 Knob Compressor in good condition—an iconic studio-style compressor that adds smooth sustain, tighter dynamics, and extra punch to any rig. Simple 4-control layout (Sustain, Level, Attack, Clipping) makes it easy to dial in subtle leveling or country snap, with true bypass switching for a clean, unaffected signal when off. Built in a rugged compact enclosure and ready for stage or studio, this pedal delivers the classic Keeley compression sound guitarists love.
