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.

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.

Absolutely Brutal Amp with Amazing Cleans!
Those looking for an amp that can also cover all styles equally well, look no further. This is undeniably a face melting amp that conjures amazing metal tones. But I consider the clean channel just as good. No need for overdrive on this beast. I really can’t overstate how good this amp sounds. Just get it. You will not be disappointed.

Metal-heads Rejoice: This VH4 has you covered!
I bought this along with the ENGL Savage 120 plug-in and I couldn't be happier. The VH4 will give you all shades of metal, from black metal and thrash to old school death to tech-death and beyond. It's equally suitable for rhythm or lead; I find it shines best when I throw an overdrive pedal/plug-in in front of it, although you can get a similar effect by utilizing the built-in FX rack Input Gain and Power Soak knobs. Mix and layer it with a differently voiced amp like the ENGL Savage 120 for incredible results. Be sure to take advantage of the huge array of impulse responses that come stock with this plug-in and you're bound to find something that blows you away.

Wonderful!
Sounds really amazing.

EXCLENTE EMULACION!!!!
Impulso rápido, sonido fuerte, contundente, crujiente, sólido y efervescente!!!. Sonido explosivo para hacer rock. Así como cristalino y limpio.
Me sorprendió!!!A. Keeler
Great sound, great response
I snagged this to compliment the myriad of amp models I’ve had and by far this is the best. Stunning tone, great response and a helpful fx rack make this a must have if you’re searching for a quick boost to electric guitars or something to re-amp with. I use it as my daily driver to practice and record with. You won’t be disappointed. Then again if you are using Universal Audio, you’re used to that.

Sounds good but needs MIDI
The sound is good, but like every amp sim with UAD, there should be MIDI in console to be able to footswitch the channels.
C. Vurnis
From clean to heavy, has all the right tones !!
Great clean channel, great crunch channel, great high gain channels !!
Hit the crunch channel hard, and there is a lot of saturation. Play softer, and it cleans up really well !!
Also, the plugin responds well to hardware boost and drive pedals in front of the interface. Can't go wrong with this plugin !!C. Billmeier
THIS SMOKES.
I was curious what this would sound like on a standard Strat or Les Paul since all the demos show 7-strings and/or very low-tuned guitars, and WOW. It sounds fantastic! Very high gain but not nearly as metallic or inarticulate as one might fear with so much juice.

Best amp sim I've played!
From the start, I have always wanted to play and record a tight, punchy, raging metal amp sound, but be able to do it silently via DI. I have tried many software amps (UA and others) and many hardware units. This has led me to a Fractal Axe FX and a Blackstar tube head running into a Two Notes Torpedo Live, and while I am still very glad to have that hardware, I might never have bought any of that if this plugin came out for UAD a few years earlier. To me, it is by far the best sounding UA amp. The cleans are great, you have tons of flavors of distortion to play with here, and exploring the huge list of IRs will almost certainly yield one or two sounds that will fit perfectly in your mix. If you have felt like amp sims (including UA ones) have not quite felt and sounded the way you wanted, I suggest you give this one a try.

Almost the real thing!
This is amazing. The range of tones from 1 amp is brilliant and I love how it responds to external effects pedals. I know these are not cheap but they are amazing value and very close to the real thing.
J. Ray
Just like the real thing and more!
I’m not too familiar with Diesel amps in general, but the tones that I’m able to get out of this thing are TOP NOTCH! I was blown away when I put it in Unison mode and got it dialed
in with a Teletronix compressor and limiter combo. Definitely worth the price even when it’s not on sale.A. Sudarkin
Passion and rage!
Sounds fantastically natural. For me, this is the best emulation in the world. Universal amplifier in all senses and styles. Indispensable thing. Recommend.

Raw as it gets
Loved this amp from the beginning. Raw and clean, you got it all right at your fingertips

Tone, and room to explore
I was just as surprised with the Tweed 55, in that the what I was hearing from the Diezel surpassed my expectations. I use the amp plugins for scratching out ideas on the fly, song ideas for initial drafts. But this amp has me spoiled ! Very responsive, with tube saturation from think crunch to a blast from the past 70’s rock. You will not be disappointed, but caution in that you just may get hooked on this being your main amp for studio work........
