Hellbert (Diezel Herbert): Demo Pack

The Hellbert is a NAM capture pack captured from a real Diezel Herbert — one of the most powerful and versatile boutique high-gain amplifiers ever made. The Herbert is a three-channel beast known for its immaculate clean tones, its aggressive crunch, and its legendary high-gain channel that has defined modern progressive and metal tones for two decades. This is the Demo Pack.

Every capture in this pack was made from the actual Diezel Herbert in a professional studio environment, captured through a professional studio preamp (NEVE 1073, API 512, or Harrison 32c), miked with Beyer M160 ribbon, Shure SM57, or Royer R121 (or a combination).
