Description

Add classic British-style punch to your tone with this used Keeley Java Boost in great condition. Inspired by vintage treble boosters, it delivers rich upper-mid bite, tighter lows, and smooth, harmonically complex drive when pushing an amp. Simple single-knob operation makes dialing in edge and volume fast and musical. Built in a compact, road-ready enclosure with true bypass switching and standard 1/4" input/output, it runs on 9V DC center-negative power for easy pedalboard use.
