Zvex has now gone to a Vertical style box for a more pedal board friendly layout. Now there is no excuse not to get a Zvex pedal and plug in. This Box of Rock™ simulates Zachary’s favorite amp turned up all the way, a 1966 Marshall® JTM45. The tone control adjusts brightness and there’s a high-headroom low-noise boost.

A favorite pedal of J. Mascis of Dinosaur Jr, the Box of Rock is a clean boost and distortion housed within one unit. Designed to emulate the tones of a classic overdriven Marshall, the Box of Rock sports separate footswitches for boost and distortion, a streamlined four-knob interface, and Zvex's signature "Distortron" distortion circuit.
