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?? :)))

Authentic Emulation

I played a VH4 through a 4x12 cab live for a while and I must admit this is quite a faithful reproduction for a plugin. I can see why it’s so popular with metal players, but I always found it to be far more than a metal amp. In my opinion one of the most versatile amps ever - and the plugin version is the same. Great plugin!

Great Amp Plug

Love it. Use it for quick demos and for monitoring when using a load box with my amp heads. Responds really well to playing and feels good. Would easily make it onto releases if needed.

Metal Monster

Having this and the Herbert available for the Unison slot makes it easy to make bone crushing metal anywhere you can take your apollo....

Tight and agressive.

Really fan of Diezel amps, playing with different IR is a great weapon in your arsenal.

An Amplifier for any situation

Need a sparkling clean, super heavy or anything in between guitar tone? This is the amp every recording musician should have in his collection.

Really good!


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!
