Zvex Box of Rock User Manual

TYPE: Vexter Series [V] | MODEL: BOX OF ROCK™

Congratulations! You’re the proud owner of a Vexter series Z.Vex Eects Box of Rock!™

OVERVIEW

The Box of Rock™ is Z.Vex Eect’s rst “distortion” pedal,
highly specialized to simulate the “everything on 10” sound
of a classic Marshall® JTM45 non-master-volume amplier.
You may use the Box of Rock™ eectively with many dier­ent ampliers. Once you’ve set your maximum needed drive
on the pedal, use your guitar’s volume control to adjust for
the exact amount of distortion you need, all the way down to
very clean and clear with most drive settings. You will notice
the words “distortron engine” on the Vexter version of this
pedal (no, that’s not a misprint) on the pedal. This is what I
named my distortion circuit... call me crazy.

The Box of Rock™ also contains an extremely high-head­room, unity-to-50X gain booster with nominal input imped­ance and low hiss. It is very similar to the SHO boost cir­cuit, with renements to make it sound more like a standard
amp input and less glassy. The boost channel can be used
alone or in conjunction with the “distortron engine” channel.
The boost channel follows the distortion channel so that the
distortion is able to hit your amp harder (at a higher volume)
when both switches are engaged, for boosting solos and
what-not. Look out when boosting what-not. 8^)

CONTROLS

OPERATION

Plug your guitar (or any eect’s output) into the right hand in-
put jack. Plug the output into an amp or other eect’s input.
Rock out. Careful with the Boost setting when using a high­powered amp with lots of headroom... you may be shocked
at how loud it can get!

The best way to complete this pedal is to run it through a
tube amplier on a warm clean setting (try strapping the chan-

nels, setting the volumes below 3, and setting all other controls to
6 as a start point), which has the proper voicing to reveal the

“rock” in the Box of Rock™.

BATTERY CHANGE

If the performance of your pedal seems diminished or the
LEDs become 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 1 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 a long battery life. Current draw is ap­proximately 3mA. A DC power jack (standard Boss congura-

tion with center negative) is provided on the side of the pedal.

Use a high-quality 9V adaptor for all high-gain eects!

based on my original Super Hard On™ gain

This is perfectly normal.
