Built with a high-impedance input, searing-hot output, and single knob that allows for up to eight volts of pure power, the Zvex Super Hard On Boost Vexter is that "always-on" pedal that fattens up your sound while retaining your rig's organic tone. The high-octane input smoothes out pups from single-coils to humbuckers, leaving pristinely-boosted sound along with a crisp added high-end clarity. A solid option for leads/solos or to keep on for continuous boosted tone.
