Diezel's Herbert amplifier is a 180-watt pulverizer designed to deliver the meanest of means, the cleanest of cleans — and more. Still considered state of the art, nearly 20 years after its release, the Diezel Herbert is a mainstay in heavy rock, and extreme metal productions — anywhere bold, powerful electric guitar tones are required. Developed by Brainworx, and officially endorsed by legendary amp builder Peter Diezel, the Diezel Herbert plug-in masterfully emulates this six KT77-equipped sledgehammer.
