Product Description

The ZVEX Effects Box of Rock is an extremely popular distortion pedal. Able to accurately imitate the iconic tones of a cranked Marshall JTM45 amp, the ZVEX Box of Rock's unique "Distortron" circuit delivers a stunning saturated sound and is extremely reactive to your playing dynamics - just as you'd expect from a vintage Marshall valve amp.

This "Vertical" version of the Box of Rock features the exact same circuitry as the original, albeit with a more conventional chassis that some players might find easier to mount on their pedalboards.

2-in-1 Design

Featuring two footswitches, the ZVEX Effects Box of Rock is essentially a 2-in-1 pedal with a boost side and full-out distortion channel. Able to use the two sides independently or together for thick unbridled gain - the Box of Rock gives you plenty of tonal options.

The ZVEX Box of Rock's high-headroom boost circuit offers plenty of extra volume, which can be controlled via the dedicated 'Boost' control. It's worth noting that the boost channel follows the distortion channel so that the distortion is able to hit your amp harder when both switches are engaged, offering a potent dose of "more" for solos and lead lines!

Marshall-Style Distortion

ZVEX Box of Rock pedal gets most of its appeal from its authentic, Marshall-style drive circuit. Punchy and clear with lots rich harmonic content, this powerful distortion channel can get the most out of practically any amplifier that it's plugged into. And once you’ve set your maximum amount of gain with the 'Drive' control, you can use your guitar’s volume control to adjust for the exact amount of distortion you need.

To influence the pedal's EQ, a single 'Tone' knob allows you to adjust the amount of treble. Keep it low for a smooth and vintage-like sound, or crank it higher to achieve and more contemporary tone with extra "bite" to cut through in a mix.
