Looking to bring a little 1966 Marshall JTM45 to your rig? The Box Of Rock is your move.

The Box of Rock 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. Once you’ve set your maximum needed driveon 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.

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.


Sets the boost level which is engaged with the left stomp switch. The Drive and Boost controls are based on the original Super Hard On gain
control so they may crackle when turned. This is perfectly normal
