Key Features
This Z.Vex Vexter Super Hard-On is the perfect preamp pedal. The "Crackle Okay" volume knob is a negative-feedback control styled after classic 60's 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 Super Hard-On's input impedance is so high 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 SHO's input jack comprises the battery switch. Please unplug from this jack to preserve battery life. After plugging in your pedal ensure it is turned it on and off a few times to equalize the voltages between your guitar, other pedals, your amp, and the SHO. Otherwise you may hear a "POP!" when you turn on your SHO during a gig. If you adjust the boost level, you may hear a "POP!" when switching too. It goes away after a few switches.
The very high input impedance of this pedal can cause strange reactions when used with vintage guitars. 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.
Please Note: The unit demonstrated in this video is the Hand Painted version of the Super Hard On, the VEXTER version offered here is exactly the same pedal only not hand painted.
