Inspired by classic Treble Booster circuits, the Cestus takes that iconic topology and tweaks it to work for all players. Internally there is a Military Spec SIlicon 2N2222A transistor that was chosen for it's great sound in this circuit.
Unlike it's Germanium brethren, this Silicon transistor version doesn't require a specific type of power and won't fluctuate in tone if the sun comes out at your next gig.
