Tsar Boost - Germanium PedalTSAR BOOST is a single germanium transistor boost pedal designed to give you classic tones, but with a few twists. First, the input impedance has been raised to the point where humbuckers can be used without suffering low end loss. Second, a versatile tone control has been added which turns the pedal into an adjustable treble boost, for those Brian May tones.
