Zvex Vertical Box Of Rock Guitar Effects Pedal

The Box of RockTM is ZVEX 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 RockTM effectively with many different amplifiers. 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. 

The Box of RockTM 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 “distortion 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^) 

Features:

• Volume - Adjust for distortion engine volume level.
• Boost - Sets the boost level, which is engaged with the left stomp switch. The Drive and Boost controls are based on an original Super Hard OnTM gain control, so they may crackle when turned. This is perfectly normal. 
• Drive - Sets the amount of distortion. 
• Tone - Adjust for treble content.
