Description

Spread the love

The ZVEX Effects Double Rock is essentially a dual-channel distortion pedal that features two 'Box of Rock' circuits within a super-compact enclosure. Dishing out punchy and saturated vintage Marshall tones with lots of rich harmonic content – the ZVEX Double Rock can be configured to offer unique blends of boost and distortion for a wide, uncompromising tonal palette!

Flexible 2-in-1 Design

ZVEX's almighty Double Rock pedal combines two Box of Rock circuits to ultimately form something more versatile than its standalone counterpart. With 'Volume', 'Tone' and 'Drive' controls (like you'd find on the standard 'Box of Rock') for each side, you can set their parameters differently so that, for instance, one channel delivers a low-gain crunch for rhythm playing, while the other offers a searing distortion sound for solos.

Boost!

But it doesn't end there though. That's because both channels can be switched from their full 'Box of Rock' distortion circuits to milder boost modes! The boost circuits are taken from ZVEX's popular 'Super Hard-On' pedal, which is a powerful yet ultra-transparent preamp that provides plenty of additional volume.

Mix & Match

With its incredibly versatile configuration, this means that you can set up the ZVEX Double Rock to have 2 distortions, 2 boosts, boost into distortion, or distortion into boost. Use any combinaton of these to create anything from a tight, boosted distortion sound to thick high-gain sludge with both distortion channels engaged. It's entirely up to you!

Flexible 'SUBS' Switches

To give you further control over the sound of each channel, the ZVEX Double Rock's 'SUBS' contour switches allow you to shelve any unwanted low-end flab with three distinct settings. Mode 1 is the most extreme, taking away lots of rumble for a focused drive sound. Mode 2 allows more low-end into your signal for extra fullness, while mode 3 gives you "everything".

Please Note: The 'SUBS' functions only work when using the distortion modes.

Distortion

Distortion pedals take your clean guitar signal and transform it into something bigger, bolder, and full of attitude. By clipping the waveform, they add sustain, bite, and aggression, creating that thick, compressed tone that’s powered rock music for decades. From the growling crunch of classic hard rock to the tight, saturated roar of modern metal, distortion is all about energy and presence. It gives every note weight and authority, pushing your amp to its limits and beyond.

There are countless flavours of distortion, each with its own texture and edge. Some sound smooth and creamy, others raw and gnarly like tearing fabric. It’s the sonic equivalent of turning up the heat until the sound cooks — rich, sizzling, and perfectly seasoned to taste. Whether used for rhythm muscle or soaring leads, a good distortion pedal doesn’t just add volume; it adds personality, grit, and that unmistakable sense of power under your fingers.

New

This is brand new, fresh in, and a UK warranty is included. New Gear always comes from trusted UK music retailers.

Preamp

A preamp pedal shapes and boosts your guitar’s signal before it reaches your amp or recording interface, giving you control over tone, gain, and headroom. It acts as the first stage of amplification, adding warmth, clarity, and character while preparing your signal for the next part of the chain. Some preamps emulate the response of classic valve circuits, while others offer clean, transparent tone shaping ideal for acoustic instruments or direct recording setups.

Used on its own, a preamp pedal can serve as the foundation of your tone, providing a consistent core sound wherever you play. When combined with other effects, it enhances dynamics and helps each pedal sound more defined and natural. Whether you’re looking to push your amp harder, bring life to a dull signal, or refine your sound for the studio, a good preamp pedal adds presence, punch, and musicality to any rig.

Volume

Volume pedals control the output level of a guitar signal using a foot-operated treadle. They allow smooth volume swells, dynamic control during playing, and easy muting between songs. Volume pedals can be placed at different points in the signal chain to either control overall loudness or adjust gain and drive behaviour when positioned before distortion or overdrive pedals.
