Keeley Java Boost

The Keeley Java Treble Boost is a treble boost guitar effects pedal that is handmade in the USA, and features true bypass. The Java Boost is a germanium based Treble Booster designed to give you classic tones from the 60’s and 70’s - it is not a clean boost. It must be used with a cranked amp that is overdriven or distorting a bit already. Cranking the amp and pedal will result in more creamy, beautiful, sustaining distortion with the Java Boost. The Java Boost is most widely used with a tube amp set to a bit of overdrive or clipping which is the key to getting a great sound from this pedal. This product 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 modes on the Java Boost.
