ZVex Effects Vexter Super Hard On Boost/Overdrive. Vexter Series pedals are lower priced, featuring silk-screened art. The parts inside Vexters are identical to the hand painted pedals. 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. Pedal Dimensions (LxWxH): 4.70" x 2.38" x 1.82" • MFSKU VSHO • UPC 855245003183
