Used Keeley 4 Knob Compressor Effect Pedal

This used Keeley 4 Knob Compressor pedal in good condition delivers the classic studio-style squash and sustain that players love, adding smooth leveling, enhanced clarity, and punchy dynamics to clean or driven tones. Simple 4-knob control layout lets you dial in compression and output quickly, while the rugged stompbox design is ready for regular gigging. Standard 1/4" input/output jacks and 9V DC power compatibility make it an easy fit on most pedalboards.
