The Z.Vex Box of Rock Guitar Effects Pedal is a designed to simulate the ‘everything on 10’ sound of a classic Marshall JTM45 non-master-volume amplifier.
The Box of Rock also contains an extremely high-headroom, unity-to-50X gain booster with nominal input impedance and low hiss. 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.
The Box of Rock uses a 9V battery (preferably alkaline, but the unit is shipped with a carbon-zinc battery).
The main features of the Z.Vex Box of Rock Guitar Effects Pedal include;
Drive: Sets the amount of distortion
Tone: Adjust for treble content
Vol: Adjust for ‘distortron’ engine volume level
Boost: Sets the boost level, which is engaged with the left stomp switch
