Chapter Four: Four Pre-Amplifiers
4.1 Pre-Amplifiers and their Functions
The Diezel Hagen comes equipped with 4 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 4 most wanted guitar tone flavors: 1-Clean, 2-
Crunch, 3-Heavy, 4- Lead or heavy riffing.
This concept delivers 4 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. Hagen 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. The
gainpot will adjust the amount of distortion here, going from a very mild crunchy sound at lower
settings to a hot rodded crunch sound when set to 100%.
4.1.3 Channel Three (Heavy)
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.
