Zvex Box of Rock (Hand painted) FF0121

Overview:
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 "distortion engine" on the Vexter version of this pedal (no, that's not a misprint) on the pedal. This is what ZVEX named their distortion circuit.

The Controls:
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 distortion 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.
