 Definition
This parameter determines the way the preamp distorts when overdriven. Every guitar amp produces a dif-
ferent kind of distortion. The “Definition” parameter controls the characteristic fingerprint of the preamp.
The profiling process automatically sets “Definition” to the position that best represents the reference
amp.
Settings on the left of the parameter range Woody, muted, bluesy, or earthy textures with a
limited dynamic range.
Settings in the middle of the parameter range Fat and creamy textures with a greater dynamic
range.
Settings at the right of the parameter range Sparkling, brilliant, interactive and boutique.
As you can see, by tweaking “Definition”, you can change the preamp distortion characteristic completely.
So you could, for example, use this control to modernize the profile of a vintage amp without having to
use additional stomps. Alternatively, start with a profile of a modern tube amp and use “Definition” to give
it a more vintage sound, when driven.
You can also use “Definition” to align the sound of your guitar to the sound of your amp, if required. Don’t
be afraid to experiment until you get the balance that sounds best to you.
