I got blisters on my eardrums, bitemarks on my earlobes.

Yep. It is ALL THAT, and the Reptile Monster it rode in on....

A multitude of tone palettes, clean to crispy, crunchy to volcanic.

This isn't your Grandmother's amp, its a perfectly ravenous creature that tears up all the rest before breakfast.

Brainworx did it again. What else can we say.

The best in UAD for guitar

As a devoted fan of Mesa Boogie, I recently tried out the VH4 guitar amp simulation, and I must say, it left quite an impression. While the VH4 has its unique sonic flavor, it satisfies me as much as a Mesa Boogie, thanks to its remarkable realism, precision, and professionalism. I was delighted to discover a wide variety of tones suitable for various styles. However, I couldn't help but feel disappointed by the absence of a built-in tuner(lost 1 star). On a positive note, I appreciate that it falls within the UNISON range, making it a versatile addition to my setup.

So many different tones

We all know most of the tone comes from the cabinet and mic choice. This amp has so many combinations that you can get any tone you want

A beast with a soft charcter

What really got me surprised was the character of the clean tones that are more than useful and convincing

The Diezel VH4 is Irreplaceable

This Amp Plug-in remains a top-flight choice for a wide variety of styles. "Don't mistake this as a metal only amp." It covers a lot ground without compromise. Put it this way. I own a pricey - not to be named amp modeler, yet I continually find myself grabbing the Diezel when I want excellent tone and feel in very short order.

Vh4 with superior sound on both the diezel amp and as an Cab impulse

I bought this to use it as a Cab Impulse for my amp heads, and it sounds very organic and real. With the power amp section using the presence and depth It gets Even better.

One could only wish for a dedicated uad Ir loader based on this VH4, but the diezel vh4 works just as good!

Great Diezel Sound

Both Diezel Amp Sims sound great, but I prefer the VH4. Channel 4 plus some EQ makes your metal sound shine

Sounds real in a mx

I love that one, even better than the Herbert. That Unison gives life to Amp Sims.

Too good to be true

The simulation is superb. UAD as always making unbelievable analog sims. I recommend it to all guitar players. This is a beast amp.

Very good but... No IRs...

I own the VH4 and the Herbert which both sound pretty good! But neither of them can support third party IRs... That is REALLY a big limitation for using those plugins live. Of course you can do whatever you want in your daw, bypass the cab section and add your own IRs afterward. But adding your own IRs, that would be a HUGE upgrade. The Apollo could definitely compete with any Axe FX or Helix.
Pretty please UAD?? :)))
