ZVEX Super Hard On

Brand: ZVEX · Category: Boost · Released: 1998

One-knob MOSFET boost that adds level, sparkle, and the kind of push that makes amps confess things.

The ZVEX Super Hard On is a deceptively simple MOSFET boost/preamp built to make the next thing in the chain react harder. It can add clean-ish level, bright presence, and amp-like urgency, but it is famous because it does not feel like a polite utility box.
