Description

Edit description

Introducing the Diezel VH4 100W Tube Guitar Amp Head, a legendary beast in the world of high-gain guitar amplification. Since its inception in 1994, this flagship amp from Diezel has been the go-to choice for rock guitarists owing to its unmatched sonic flexibility and authoritative tonal output.

The VH4 boasts of four independent channels - Clean, Crunch, Mega, and Lead, each one offering a unique tonal range and character. The Clean channel shines with Diezel's signature sparkling chime, while the Crunch channel delivers classic rock rhythm and leads. The high-gain Mega and Lead channels are where the VH4 truly showcases its mettle, offering everything from chunky rhythms to searing solos.

Designed with the modern guitarist in mind, the VH4 doesn't stop at delivering a formidable preamp. It also features a 100-watt power amp driven by four KT77 power tubes, parallel and series effects loops for maximum tonal flexibility, and MIDI switching for easy integration into complex rigs. A global presence control and a "Deep" control make further tone sculpting a breeze.

As durable as the tones it produces, the VH4 is housed in a steel chassis with an aluminum faceplate. Each power tube features an independent fuse and fault indicator light, ensuring many years of flawless performance.

Channel 3....what else!

The channel that this amp is famous for is responsible for 70% of The Prophecy's distorted tones since 'Into the Light' - often blended with a more aggressive and less refined amplifier in the studio. The VH4 provides the champagne smooth saturation to Greg's Engl Savage or Laboga Mr. Hector throaty dirt when layering multiple layers or distortion or recording with dual amplifiers from a single D.I/live guitar.
