Zvex Vexter Box of RockZvex
A two-in-one powerhouse from ZVEX, the Box of Rock is meant to simulate the sound of a cranked Marshall stack. The right footswitch controls the “Distortron” circuit, which is ZVEX’s proprietary gain stage. The Volume, Tone, and Drive knobs sculpt the Distortron to give you just the right amount of crunch without losing any definition or girth in your tone. The footswitch on the left controls a high-headroom boost that feeds into the Distortron engine, exciting the transistors even more and pushing you into higher gain territory.
