The ZVEX Double Rock pedal was originally designed for J. Mascis of Dinosaur Jr. He requested two Box of Rock™ pedals in one box with two stomp switches. He uses that regularly on stage now, but ZVEX did one (or two) better with the one production model... Now, you can adjust the sub frequencies (like the Distortron™), and you can convert either channel to a Super Hard-On™. In this way, you can configure the pedal to be two Distortrons cascaded, two Super Hard-Ons cascaded (like a Super Duper 2-in-1™), or a Box of Rock™ with boost, or a Super Hard-On™ (SHO) going into a Box of Rock™. Distortion/boost heaven! Whee!!! Let’s go over the controls:
Sets the amount of distortion in Distortron™ mode, and sets the amount of boost in
It may crackle when turned. This is perfectly normal.
Adjust for treble content. Start around 2:00 o’clock. This knob only does stuff in Distortron™ mode. VOLUME: Adjust for output volume level.
DIS / BOOST Switch:
Changes the circuit from a Distortron™ to Super Hard-On™ boost.
“2-1-3” lets you choose the full “Box of Rock” sub amount (3) or two different lower levels of subs depending on your amp’s needs. Only works in Distortron™ mode.
