Used Keeley 4 Knob Compressor Effect Pedal

Used Keeley 4 Knob Compressor in great condition, delivering the classic studio-style squash and sparkle guitarists love. Simple 4-control layout (Sustain, Level, Attack, Clipping) makes it easy to dial in smooth country snap, punchy funk, or transparent leveling. Built in a rugged compact stompbox enclosure, it runs on standard 9V DC power and features true-bypass switching for a clean, unaffected signal when off. Perfect for tightening dynamics and adding sustain.
