The Super Hard On, or SHO as we fondly refer to it, is an ultra-transparent boost that goes from unity gain to a whooping 60 times the original size (watch out!), while adding a delightful high-end clarity with its 5 million ohm input impedance. Vexter Series pedals are lower priced, featuring silk-screened art. The parts inside Vexters are identical to the hand painted pedals.
