An absolute monster combination of tone and features.

The VH4S is an all-tube amp with four individual preamps, integrated midi-switcher and much more.

The clean channel is one of the best in the industry, with plenty power and lots of percussive, piano like punch.

The crunch channel is very pleasing for bluesy play or with less gain to resemble a vintage clean tone. Crank the gain up and it becomes a nice broad and open crunch a'la AC/DC.

The third channel (heavy) is simply unbelievable. It has big dynamic ranges, from playful little licks, tasty solo work, to all out metal gain. The tone will not lose definition, though. Even at high gain selections, with humbucker guitars, it speaks straight from the artist's fingers. This channel is easy to play for the intuitive. It cleans up with guitar volume rolled off, and then comes on like a freight train when needed.

Channel four starts where three leaves off. If gain is your thing, then channel four is sure to please you. It compresses more than three, retains definition to a large degree, and just shreds with big bass and strong high end. It is smooth distortion, creamy but authoritive. Loud.

The power stage of the DiezelVH4 is either mono or stereo, depending on which model you choose. VH4 is the mono amp, VH4S has stereo power and stereo effects returns. Each tube has a tube fault indicator, and a separate fuse. In case of tube failure, the fuse blows and takes the duet out of the circuit. You will finish your set with two tubes, instead of a dead amp.

The power amp has a master volume, presence and deep controls. There are parallel and serial returns to the power amp. Two sends give you flexibility far beyond any standards. One of the sends is front panel/midi switchable. The parallel return has a mix control on the front panel in the master section. Oh, not to forget the channel inserts for channel one through four. These can be manually or midi controlled. The Diezel Midi system has 16 channels, with 128 program changes.

      Comments about Diezel VH4S 100W Tube Guitar Head:

      I bought this amp when it first came out. I was one of many who just had to have the new kid in town. This amp just does not have any sparkle to it, especially channels 2,3,4. If you like a very crisp and crunchy tone that cuts great in any situation, look elsewhere. I found this amp to be too dark, too compressed, with no character or soul. It also lacks sustain. If you want to drop this kind of cash on an amp, the Engl SE will trump this amp on all aspects, all day long. Right now I am considering the Engl Richie Blackmore, Engl Victor Smolski, Engl Invader 2. All of these amps will leave any Diezel wishing it could be those amps when it grows up. And, look no further than Musician's Friend for your gear needs, best prices, best deals (No I do not work for the company).
