The Super Hard-On from ZVex is an outstanding preamp pedal that is so transparent, no one will be able to tell you're using a pedal. "Crackle Okay" volume knob that has a negative-feedback control styled after classic '60s recording console inputs. (They crackled when adjusted, too.)
Most vintage guitars suffer from steadily deteriorating magnets in their pickups, since permanent magnets aren't really forever. The ZVex Super Hard-On's input impedance is so high (>5 megohm) that it refuses any current flow from your pickup, maintaining the most magnetic field around each string so you can hear exactly what your pickup sounded like the day it came off the winder. The output level can exceed 8 volts peak, and when it finally distorts, the wave is shaped like triode overload, not fuzz.
The Super Hard-On overdrive pedal makes the most of a classic amp and guitar, because it simply makes your guitar bigger and pushes the amp harder, causing natural overload. This sound can be the solution to the "disappearing guitar" effect you get sometimes on stage when you stomp on your distortion and sound weaker. When cranked, it sounds much louder than a fuzz or distortion under stage conditions.
Like all ZVex pedal designs, current flow is low in this circuit (less than 2mA), enhancing battery life. The circuit board is hand-cut and soldered with the critical component, a BS-170 MOSFET transistor, placed in a socket for easy user replacement should it be necessary.
The box is hand-drilled using no petro lubricants and hand-painted, so every box is unique. Knobs are Harry Davies, made with the same molds they've used since the '50s. Each effect is hand-dated and signed by Zachary Vex.
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. Each Super Hard-On is unique in its reaction and optimized for the major brands.
