Zvex Double Rock 2015 s/n D067 Hand painted in USA, One of one in mint condition with box, case candy and manual.

OVERVIEW:
This pedal was originally designed for J.Mascis of Dinosaur Jr. He requested two Box of RockTM pedals in one box with two stomp switches. He uses that regularly on stage now, but we did one (or two) better with the one we’re releasing to the public... we made it so you can adjust the sub frequencies (like the DistortronTM), and you can convert either channel to a Super Hard-OnTM. In this way, you can con g- ure the pedal to be two Distortrons cascaded, two Super Hard-Ons cascaded (like a Super Duper 2-in-1TM), or a Box of RockTM with boost, or a Super Hard-OnTM (SHO) going into a Box of Rock TM. Distortion/boost heaven! Whee!!! Let’s go over the controls:

CONTROLS:

DRIVE: Sets the amount of distortion in Distortron TM 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 TM mode.

VOLUME: Adjust for output volume level.

DIS / BOOST Switch: Changes the circuit from a Distortron TM to Super Hard-On TM 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 TM mode.

OPERATION:
Plug your guitar (or any e ect’s output) into the right hand input jack. Plug the output into an amp or other e ect’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 TM or Su- per Hard-OnTM by way of the “DIS / BOOST” toggle. When
in Distortron TM 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.

PEDAL PLACEMENT:
I recommend that you try the Double RockTM last in your pedal chain, just before the amp. You can set the amp for your favorite clean tone, and set the Double RockTM for your favourite distortion/boost tones. Since you can change the rst or second stomp switches to either a Distortron TM or Super Hard-OnTM (SHO), you can mix and match the two to experience different results... SHO before the Distortron TM 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 intendedby going Distortron TM into Distortron TM or get Super Duper 2-in-1TM 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 RockTM. 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 ampli er 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.)

BATTERY CHANGE:
If the performance of your pedal seems diminished or the LED becomes very dim, it’s time to change your battery. Remove the four screws on the bottom of the pedal and carefully remove and replace the old battery, putting it back exactly in the center of the pedal on edge so that it is gripped tightly by the lid when it is screwed back in place.

SPECIFICATIONS:
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 batterylife. 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!
