Get the High-Gain sounds of Tool and Metallica along with Gorgeous Cleans

Introduced in 1994, the VH4 amplifier was Diezel's maiden voyage — a 100-watt beast that dropped jaws with articulate cleans, dynamic distortion, and frothy high-gain tones. Still a modern tone giant 25 years after its release, the Diezel VH4 is ubiquitous in heavy rock and metal productions, used by Tool, Metallica, and tons more.

Developed by Brainworx, and officially endorsed by legendary amp builder Peter Diezel, the Diezel VH4 plug-in masterfully emulates this four KT77-equipped 100-watt beast, for UAD hardware and UA Audio Interfaces.

Access Four Channels of Unlimited Tones

Featuring Clean, Crunch, Mega, and Lead channels, the Diezel VH4 plug-in faithfully captures the original amp's glorious sparkling clean tones, simmering medium-gain sounds, and absolutely searing lead textures. No matter what guitar you plug in, the Diezel VH4 plug-in gives you all the tonal touchstones you need to record dynamic, modern guitar sounds.

Take Complete Sonic Control

The Diezel VH4 plug-in offers additional control over your tones via the Brainworx FX Rack. It features a Noise Gate, switchable high and low-pass filters, and a Power Soak circuit that allows you to dial in as much overdrive as you want, without having to crank the output gain.

The Diezel VH4 plug-in also includes 120 impulse response Recording Chains that were perfectly captured from several boutique cabinets and recorded through Brainworx's vintage Neve console with an array of high-end and vintage microphones and outboard gear, giving you "record ready" tones, instantly.

Get Ultimate Accuracy with Unison™ Technology

Harnessing UA’s groundbreaking Unison technology, the Diezel VH4 plug-in gives you the impedance, gain staging, and circuit behaviors that have made the VH4 one of the most lusted-after tube amps ever made.
