Hand-built overdrive guitar effects pedal that has incredible dynamics, full range and is very responsive. It is based on one of the earliest Keeley modified pedals – the BD-2 Blues Driver with wonderfully complex circuit that has many layers of JFET tube amp simulation, but has an added germanium amplifier stage right after the tone stack to simulate a tube power amp section, creating a perfect of combo of fuzz and overdrive. The pedal features Level, Tone and Drive controls, Flat/Phat switch and the Germanium Super Phat Mod footswitch.
