Originally designed for J.Mascis of Dinosaur Jr., the ZVex Double Rock is now much more!

This 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 released to the public... they made it so 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!

  • DRIVE: Sets the amount of distortion in Distortron mode, and sets the amount of boost in SHO mode. It may crackle when turned. This is perfectly normal.
  • TONE: 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.
  • SUBS Switch: "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.

Plug your guitar (or any effect’s output) into the right hand input jack. Plug the output into an amp or other effect’s input. Rock out. The two separate stomp switches control whether or not the two distinct circuits are engaged. You can select whether or not the circuit is a Distortron or Super Hard-On by way of the "DIS / BOOST" toggle. When in Distortron mode, set the subs switch so there's just enough low-end for your amp. Try using your rhythm pickup with the tone control turned all the way down for a vintage bluesy howling lead sound.

Its recommended that you try the Double Rock last in your pedal chain, just before the amp. You can set the amp for your favorite clean tone, and set the Double Rock for your favorite distortion/boost tones. Since you can change the first or second stomp switches to either a Distortron or Super Hard-On (SHO), you can mix and match the two to experience different results... SHO before the Distortron will give you more sustain, while after will give you more amp volume (or drive, if you use a distorted amp sound.) Of course, you can use the pedal the way J. Mascis intended by going Distortron into Distortron or get Super Duper 2-in-1 tones by cascading the SHOs. If you have other distortion pedals, don’t leave them in the closet! Many distortion pedals sound amazing into the Double Rock. You may discover a whole new love for your old distortion pedal collection!

The best way to complete this pedal is to run it through a JTM45 Marshall amplifier head/cabinet on a warm clean setting (try strapping the channels, setting the volumes below 3, and setting all other controls to 6 as a start point.)

Uses one 9V battery (preferably alkaline, but the unit is shipped with a carbon-zinc battery.) The low current operation of this pedal’s circuit will give you extraordinarily long battery life. Current draw is approximately 2mA. A DC power jack (standard Boss configuration with center negative) is provided on the side of the pedal. Use a high quality 9V adaptor for all high-gain effects!

*This pedal is HAND PAINTED, as such no two will be EXACTLY alike. Your Hand Painted Double Rock may differ from the one pictured*
