Buy Extended Service Plan ( What This? )
The Java Boost is a germanium based treble booster, it is not a clean boost. It is designed to give you classic tones from the '60s and '70s. It must be used with a cranked amp that is overdriven or distorting a bit already. The more the amp and pedal are cranked, the more the creamy, beautiful, sustaining distortion there will be. It is a Treble Booster by design, not a typical overdrive or distortion pedal. That means, the higher the note played, the more it gets amplified... and then, by your amp, distorted. Bass notes get cut in two of the modes on the Java Boost!
