When musical architect Peter Diezel created the DIEZEL VH4 in 1994 he unknowingly sparked a revolution in tone, creating such a demand that he literally had no choice but to put his own personal creation into production.
James Hetfield (Metallica), Adam Jones (Tool), and Neal Schon (Journey) are just a few of the names that have found their signature tones within the fire-breathing tubes of a Diezel VH4 head’s legendary third channel. With the VH4-2 preamp/overdrive pedal, Peter Diezel went to great lengths to faithfully reproduce that exact same tone and feel, allowing you to place it snugly on your pedalboard. But he didn’t stop there. This pedal’s two foot-switchable channels - carefully voiced for rhythm and lead tones - as well as its ability to run in front of a clean amp or directly into a power amplifier effortlessly turn any clean amp tone into a massively versatile high-gain monster. The Diezel VH4-2 preamp/overdrive pedal unleashes one of the most important high-gain tones in history with the tap of your toe.
A VH4 at your feet
The VH4-2 recreates VH4 amp channel’s magical blend of aggression, clarity, and full-throated punch with the authenticity that only Peter Diezel can offer. And like all Diezel Amplification products, inside you’ll find the same commitment to top-tier craftsmanship and the only the finest-quality components. Plug in a VH4-2 and turn your amp into a raging VH4 stack.
