Here is a KEELEY JAVA BOOST in excellent used condition. Shows very light wear from use. If you are looking, you must know: It has the super rare germanium transformer that was used in early legendary treble booster circuits. It has three boost modes: 1) the Treble Master type treble booster (which is the heart and soul of this pedal), 2) Full frequency boost (great for cleaner amp settings), 3) Mid boost (more compressed and hotter).Will pack well and ship fast. Let me know if you have any questions.
