Z. Vex Vexter Super Hard-On


Z. Vex

Makes your guitar sound bigger and pushes your amp harder.

The ZVex Vexter Series Super Hard On is an ultratransparent boost that goes from unity gain to an over 8-volt peak, while adding a delightful high-end clarity with its 5 million-ohm input impedance.

The Vexter Super Hard On boost has a high-impedance input that refuses any current flow from your pickups, maintaining the magnetic field around each string and allowing your pickups to sound like the day they came off the winder. Its ultrahigh output then drives your amp into natural overload, solving the mystery of the disappearing guitar tone once and for all! The output level can exceed 8 volts peak, and when it finally distorts, the wave is shaped like triode overload, not fuzz.

The Vexter Super Hard On is perfect for making the most of a classic amp and guitar, because it simply makes your guitar bigger and pushes the amp harder, causing natural overload. When cranked, it sounds much louder than a fuzz or distortion under stage conditions.

WARNING: The very high input impedance of this pedal can cause strange reactions (sometimes mildly pleasant and/or arousing) when used with a vintage 'junk' (read 'cool') guitar. The solution is to simply lower the 'Crackle Okay' gain knob a little or leave the guitar volume wide open. Any problems will only occur at the highest gain settings with an unusual guitar.
