The Diezel Herbert is a 180-watt head with three completely independent channels, each with separate EQs, built from a clean sheet of paper to deliver delicate dynamic shimmer, detailed focused crunch, and aggressive soaring lead tones effortlessly.

This is the Mk1 — the original version, before the Mk2 revised the clean channel and power transformers. The Mk1 is widely considered to have a more organic, player-responsive feel, and commands strong demand among players who know the differences between versions.

Channel 1 is the classic Diezel clean — massive headroom, crystalline sparkle, articulate mids. Channel 2 covers everything from barely-hairy to Sasquatch crunch via a dual voicing switch. Channel 3 starts in high-gain territory with excellent picking sensitivity and note control — percussive, ferocious, and simply brutal.
