The ZVEX Double Rock is a versatile distortion and boost pedal, originally designed for J. Mascis. This pedal combines two Box of Rock circuits into one unit, offering flexible configurations like cascaded distortion, boost, or a combination of both. It allows users to adjust sub frequencies, similar to the Distortron, and also features a Super Hard-On circuit for added versatility.
Vexter Series pedals are lower priced, featuring silk-screened art. The parts inside Vexters are identical to the hand painted models.
