Diezel VH4 Amplifier
-
A carnivorous high-gain classic
with gorgeous clean tones.
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.Now You Can:
Use your UA Interface to track through the Diezel VH4 — with near-zero latency
Audition 120 separate high-end recording chains, featuring multiple cabinets and classic microphones
Shape tones further with FX Rack’s Vintage Delay, noise gate, high/low filters, and more
Easily dial in insane high-gain tones, dynamic distorted textures, and pristine cleans, with Diezel's original state-of-the art tone machine
Take a Listen
Four Channels, Tons of 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.
Diezel FX Rack
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.
Unison™ Technology for UA Audio Interfaces
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.

Really good!
Nice! This was my first purchase after getting the Apollo Twin Duo Usb. Mainly, I wanted to get this for guitar monitoring with zero latency when tracking but I was surprised how good...

Really good!
Nice!
This was my first purchase after getting the Apollo Twin Duo Usb.
Mainly, I wanted to get this for guitar monitoring with zero latency when tracking but I was surprised how good it sounds! I have Neural DSP plugins and to my ears this is as good as those.
Here´s my recording chain if I want to experiment with different IR:s and record the Diezel amp.
Put Diezel into Unison slot.
Turn off the cab section and mute the track.
Send it to AUX1 or AUX2 --> put Diezel on Aux (poweramp off and Cab on).
Monitor thru AUX.
Now the monitoring is with full rig and only the amp signal is recorded.
Put your IR loader on DAW track and experiment with different IR:s to find a tone you like.
Good job UAD!E. Kocol

Best amp and best emulator ever!
I'm not a guitarist, but I'm a sound engineer and in my ears Diezel VH4 amp is the best amp money can buy, and UAD made it again and it's sounds as the real think, I don't own the original to make A-B but I've worked with the amp for a long time as some of my clients own it and I'm getting all the feeling I had with the amp. I've use the plugin even with jazzy and bluesy guitars and it sounds great and if you want to go wild this is the way! It's not just recommended, It's a must, you need it!

High quality lead
Really impressed with the modeling. It’s like getting a new amp for a fraction of the cost.

Raw power...
Awesome emulation with a broad range of tones and virtually limitless array of cabinet possibilities. I instantly gravitated towards this one, as much for the high gain as crunch and clean...much like the real amp, it has a tonal signature all it's own. They somehow managed to almost completely eliminate that tell tale upper mid hump present in so many other amp sims. You know, the one you try to scoop out, but find it almost impossible to dial out while retaining any power and intensity. The VH4 is tight, but less processed/compressed sounding out of the gate (noise gate pun intentional?). Stays that way, no matter what extremes you go to. I'm way less compelled to put channel strips and effects after it as a result. It's beautifully raw and brutally honest (in a good way) standalone. However, if you do mess-n-compress with it downstream, things tend to get huge instead of harsh. My favorite so far.

Awesome
I got my Blueface Diezel VH 4 in 1996,when I turned 30 and was lucky that Peters workshop was a mere 2 minutes away from my studio. I still have and use my VH4 in my studio everyday, it is my go to amp and when I got mine, I had it tweaked from Peter Diezel himself who put KT 77s into mine, blew it up to 150w so that I 'd have (even)more headroom and clarity. I must say that this plug in by Brainworx is the REAL DEAL as it truthfully is a blueprint when compared to my amp head. I a/b'd them both with an astonishing lack of difference.If I feel like dialing in my signature vh4 tones whilst traveling , I can now take the emulation. Well done!

pura dinamite
Sono entrato da poco nel mondo uad e sono rimasto stordito e incredulo dalla qualità dei suoni a latenza zero. Questo diezel vh4 ha una gamma di suoni che va dal clean, molto bello, al rock, metal e metal estremo. Non credo si possa volere dipiù. Senza menzionare una miriade di cabinet con cui giocare e regolazioni infinite. L'analogico ha i giorni contati.

Awesome!
Love it with Unison, but also as a Re-Amp!
D. Reilly
The most versatile in the entire collection
Between the 4 channels of you can go from the cleanest of cleans to the maddest of mads. This amp also contains the best selection of IR's from any of the brainworx created UA amps. Turning off the power amp/IR and outputting into a real poweramp and cab has brought a new dimension into my sonic pallette. I literally dont use pedals anymore. Its worth it alone just for the preamp.

Is it a movie title or the description af UADs Diezel VH4 Amplifier? Both, perhaps?

Best Amp Emulator for Rock/Metal
I'm blown away by the accuracy of this amp emulator when compared to the real thing. This is my go to amp from now on.

Looking for an easy authentic metal amp
I bought the 2 Diezel amps for my collection, they both deliver every time

Versatile and deep-dive options!
I think this is one of the best amp plugins available. You think Diezel, you think blistering high-gain, but this is no one-tricky pony. The amp is much more versatile than I imagined. That aside, there is so much more to unpack in this plugin: dozens of cab IRs, mics, consoles, a delay, and so on. This is definitely a must-have.
