Used Keeley 4 Knob Compressor Effect Pedal

This used Keeley 4 Knob Compressor pedal is in great condition and delivers studio-smooth compression with classic Keeley clarity. Four intuitive controls (Sustain, Level, Attack, and Clipping) let you dial in subtle leveling, punchy country snap, or singing sustain without sacrificing dynamics. Built in a rugged metal enclosure with standard 1/4" input/output and 9V DC power, it’s an easy upgrade for clean tones, funk rhythm, and lead work.
