The Keeley Electronics Java Boost brings back the same incredible response and sound quality of the heralded late '60s treble boosters such as the Dallas Rangemaster. Now, Keeley gives you more control over the frequency range and gain boost. It's made with top quality components including the NOS Mullard OC44 transistor, used in the 60's classic. Drive your tube amp over the top with a creamy overdrive that's rich in harmonics and sustain! Comes with Cream colored knobs and violet LEDs and is True Bypass.
