Used Keeley 4 Knob Compressor Effect Pedal

Used Keeley 4 Knob Compressor in great condition, delivering classic studio-style compression in a compact stompbox. Simple 4-control layout (Sustain, Level, Attack, Clipping) makes it easy to add smooth sustain, punchy dynamics, and subtle peak limiting for guitar or bass. Built in a rugged metal enclosure with standard 1/4" input/output jacks and 9V DC power for easy pedalboard integration. A reliable, tone-friendly compressor for clean or driven rigs.
