Vicious modern distortion combined with huge clean tones.

Diezel's Herbert amplifier is a 180-watt pulverizer designed to deliver the meanest of means, the cleanest of cleans — and more. Still considered state-of-the art, nearly 20 years after its release, the Diezel Herbert is a mainstay in heavy rock, and extreme metal productions — anywhere bold, powerful electric guitar tones are required.

Developed by Brainworx, and officially endorsed by legendary amp builder Peter Diezel, the Diezel Herbert plug-in masterfully emulates this six KT77-equipped sledgehammer, for UAD hardware and UA Audio Interfaces.

Now You Can:

Use your UA Interface to track through the Diezel Herbert — with no 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 god-like clean tones, manicured medium gain, and all out assault with a state-of-the art tone machine

A contemporary tube amp if there ever was one, the Diezel Herbert plug-in thoroughly captures the hardware's cutting-edge circuit. From impossible-to-distort piano-like clean tones to searing early-VH textures, to absolutely groundbreaking extreme high-gain tones, the Diezel Herbert plug-in is the one-stop-shop for tracking bold, modern guitar tracks.

The Diezel Herbert 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 Herbert 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.

Its. A. Herbert. Nuff said.

Can make totally crushing guitar tones with this thing, and thank goodness it doesn't involve a 150 watt amp sitting in the room with you. Way easier to lift the Arrow to get this sound, so I'm giddy with the types of sounds I can get. I can go from hair to prog to pumpkins to even a really nice clean which is not exactly what you think of with this tpe of amp.

Great Touch-Sensitive & Versatile Plugin!

I own most of the UAD guitar plugins (and many plugins from most other developers) and have to agree with my colleague's assessment -- this may be the single best (reasonably priced) guitar plugin available today. I find UAD plugins to be the most expressive and touch sensitive, and the Herbert raises the bar beyond the high standard set on the Fuchs plugins. Most astonishing is how versatile this plugin is -- I'll be recording a pretty diverse range of material today from jazz to rock to funk to country and I'm going to try using the Herbert for all of it. Sure a lot easier to move and mic than stacks of Fenders, Engles and Marshalls ... Thanks UA!

The best so far...

This is the best amp plugin I've tried so far... I really like the range of clean to wildly over-driven.

One of the best

I have a ton of amp sims, IK, Bias, Brainworx (native), UAD, Overloud, Waves, etc. This is among my top 3 favorite, along with UAD Marshall Silver and Nembrini BST100. I can get great clean, crunchy classic rock, southern rock sounds, and full on metal. Responds great to picking dynamics.

Very usable plug in.

What impresses me most is how versatile this amp can be. From heavy crushing metal to beautiful clean tones. Cabinet/mic choices are great as well. Very usable plug in.

My favourite of all the uad amp sims

I Love channel 2 on the uad Diezel Herbert. My former studio partner had a Diezel Herbert with the matching 4x12” in our studio for about 3 years, and this is pretty damn spot-on! It does the Adam jones / Tool thing very well, and the Weezer Rivers Cuomo thing well. Four stars from me. My only complaint is that I want to be able to patch a footswitch into my Apollo so I can use it live and actually use all 3 of the channels in real time.
(Let’s make it happen!)

It’s everything I needed it to be.

I bought this to match some Metallica tones from the newer albums. And it’s spot on with some tweaking. The Mesa cabs are an awesome addition as well. Not much overhead on the pre amp but using the power soak saves your headroom. Get it!! It replaced my current amp sim - Bias.

Close Your Eyes and Tell Me the Difference!!!

As an owner of a Fortin, and a Diamond, I know what these monsters sound like - more importantly, FEEL like. I have played on a Hebert and a V4, I had certain expectations of what this plug was going to sound and feel like. There are some GREAT amp sims out there...but this blows them out of the water. It must be the UNISON tech, but seriously - I just don’t think you will find anything that will get you this close and nearly indistinguishable (in a mix you wouldn’t be able to tell the difference, and a non-musician listener would NEVER be able to tell) from the real deal. And it’s not just for ripping your head off, the cleans are NIIIICE!

Great value

This is a really great amp sim. The included cabinets work great and it’s a very (suprisingly) versatile amp. Highly recommended.

The TONES in this amp sounds like your playing a real amp extraordinary

I’m not a guitar player but I’m a sound engineer and in my ears Diezel amps are the best in their category. I’m amazed with this plugin, it has so many futures and cabins with mic compilations that is sure you will find the sound you are looking for. I didn’t believe that I would say that but I prefer this plugin over my real mesa boogie that I have in my studio.
