The Box of Rock (TM) is Z.Vex Effect's first "distortion"
pedal, highly specialized to simulate the "everything on 10"
sound of a classic Marshall ® JTM45 non-master-volume amplifier.
You may use the Box of Rock effectively with many different amplifiers,
but to get the sound I heard when I designed it, try it through a Marshall
at least once. You may 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. On the hand-painted version, the stomp switch on the right is
labeled "ROCK" instead, because our paint brushes are too
wide for so many small letters.
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 refinements 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.
Operation: 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. Careful with the Boost setting when using a high-powered
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 Marshall
amplifier 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), which has the proper voicing to reveal the "rock"
in the Box of Rock.
Features
Drive: Sets the amount of distortion. Start around 1:00 o'clock
.
Tone: Adjust for treble content. Start around 2:00 o'clock.
Vol: Adjust for distortron engine volume level. Start around
9:00 o'clock.
Boost: Sets the boost level, which is engaged with the left
stomp switch. Start around 11:00 o'clock. The Drive and Boost controls
are based on my original Super Hard-On gain control, so they may crackle
when turned. This is perfectly normal.
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 configuration with
center negative) is provided on the side of the pedal. Use a high- quality
9V adaptor for all high-gain effects!
