CV7003 OC44 VERSION. Used Keeley Java Boost in Excellent condition—an ultra-musical, vintage-style treble boost inspired by classic Rangemaster tones. Add shimmering top-end, tighter lows, and extra harmonic bite to push tube amps into rich overdrive or help solos cut through the mix. Features a simple single-knob Boost control, true bypass switching, standard 1/4" in/out jacks, and runs on 9V DC center-negative power (no battery). Perfect for rock, blues, and classic tones.
