Zvex Super Hard On Vexter

ZVEX Super Hard On. 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 (>5 Meg) 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.
