Used Keeley 4 Knob Compressor Effect Pedal

Used Keeley 4 Knob Compressor in good condition, delivering the classic studio-style compression guitarists love. Simple 4-control layout (Sustain, Level, Attack, Clipping) makes it easy to dial in smooth sustain, tighter picking dynamics, and added punch without squashing your tone. Built in a rugged metal enclosure with standard 1/4" input/output and 9V DC power (center-negative), it’s a dependable always-on pedal for clean, country, funk, and lead work.
