Stack Section; Amplifier - Kemper Profiler Main Manual

Stack Section

The stack section is the heart of the PROFILER. It represents the raw virtual guitar amplifier and guitar cabinet as
defined by the PROFILE. Every PROFILE is represented by the three modules that make up the stack section.

Amplifier

The AMPLIFIER button calls up a list of parameters that allow you to change the character of the Amplifier PROFILE
in numerous ways using the soft knobs.

Definition
The "Definition" parameter controls the characteristic fingerprint of the preamp. The PROFILING process
automatically sets "Definition" to a value that represents the reference amp. You could, for example, use it to
modernize the PROFILE of a vintage amp without having to use additional effects. Alternatively, start with a
PROFILE of a modern tube amp, and use "Definition" to give it a more vintage sound when driven into distortion.
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
keep experimenting until you get the balance that sounds best to you.
Vintage amps distort the lower harmonics in the guitar signal which gives them their bluesy sound. These amps were
originally designed to deliver a clean sound, so if you want a creamy distortion, these amps need to be driven by a
typical transistor-based device like a treble booster. Modern tube amps use a different approach, in which the higher
overtones of the guitar strings are the driving force for the distorted sound. The expensive boutique amps take this
concept one step further, by providing an extreme level of top-end frequencies and a large dynamic range. The
