Diezel VH4 VS Herbert (direct comparison)

In this comparison we're pitting the Diezel VH4 and Herbert amp heads against one another. These are both high-end and high-gain boutique amplifiers, built by Diezel Amplification, a small company based in Germany. 

We know that both amps are fairly expensive, but what are the differences between them? 

The main section of this comparison is made up of the following tables, which allow you to compare the two amps side by side with pricing and basic features.

After that, we'll get into some of the details of both amps.

Detailed Specs Side-by-Side

Diezel VH4 Details

The Diezel VH4 is the flagship model from Diezel, popular with modern rock pros like Korn, Tool, Alter Bridge, and many others. It's also one of the more expensive options, retailing around $4400 if you buy one brand new. 

It uses more tubes in the preamp, while Herbert uses more in the power amp, though both use a blend of 12AX7 and KT77 tubes. 

At 100W the VH4 isn't as loud as the Herbert (180W).

Though it's worth noting that any amp over 100 watts is going to feel and sound quite loud. 

A small advantage the VH4 has over the Herbert is the extra channel (four in the VH4 vs three in the Herbert). Both amps give you at least a three-band EQ for each channel.

Diezel Herbert Details

The Herbert drops you down to three channels and dedicates one for your clean signal, leaving out the gain knob entirely. Gain is added back into the next two channels while presence, deep, and mid-cut are controlled at the master level.

While it is higher wattage than the VH4, there isn't much that sets it apart outside of some minor tweaks and spec differences. 

We also noticed that it's oddly heavier (weighs more).

In terms of sound and tone quality, both amps sound excellent and handle particularly well with higher gain levels (one of Diezel's specialties). Both heads do a great job of giving you warm, tube tone with a modern and heavy bend. 

But, are there reasons to choose the Herbert over the better-known VH4? 

Unless you want the additional wattage, not really.

Summary of Comparison

Without that wattage difference, there's little to distinguish the two amplifiers. But we like the VH4 better, just because it's a better-known amp that a lot of pros trust. It's also just slightly more expensive than the Herbert.

If the Herbert had dropped more off the price tag, then we'd give it the nod just because it would be saving you money.

But both amps are over $4000.

Not to take anything away from the Herbert - it's a great amp - but we'll give our vote to the VH4 to get the extra channel and the additional gain control.
