Chapter Four: Three Pre-Amplifiers
4.1 Pre-Amplifiers and their Functions
The Diezel Herbert comes equipped with 3 different and totally independent preamps. This
allows the artist to play every conceivable musical style without having to make major
changes to his or her amplifier. The preamps are voiced to deliver the 3 most wanted
guitar tone flavors: 1-Clean, 2-Crunch/Heavy 3- Lead.
This concept delivers 3 stellar guitar sounds with excellent playability, warm dynamics and
razor sharp equalization possibilities. The tone controls work in an unusually wide range, so
a little adjustment goes a long way. As with so many other things - less is often more. We
suggest you start exploring the channels with all controls set to 12:00 o’clock, and the
master volume just slightly cracked open. (To avoid hearing damage)
4.1.1 Channel One (Clean Tone)
Clean Tone is a very sensitive subject, because there are so many different ideas on how
a clean amp should sound like. Clean tonal textures require much higher dynamic range
than distorted sounds. From hard and percussive sounds to soft and warm blossoming
tones. Herbert was designed to offer as many of the clean variety as possible. Your choice
of guitars and pickups will have a large part in this equation.
4.1.2 Channel Two (Crunch)
This channel’s main objective is to cover soft and heavy overdrive and distortion sounds. It
features a voicing switch, with -/+ settings. With the (-) setting selected, blues and classic
rock sounds can easily be realized. The (+) setting kicks everything up a few notches and
offers crunch with a good bite, allowing you to dial in punchy heavy rhythm and searing
solo tones.
4.1.3 Channel Three (Lead)
This channel is voiced for highly articulate single note lines or for very heavy and massive
rhythm guitar. Due to its slight midrange accent and very high gain structure, it possesses
good punch and will, with ease and authority, rule any stage or studio. The “less is often
more” rule applies here also.
