Stack Section 141
 Volume
This parameter can be used to balance volume gaps between different PROFILEs. The Rig named “Crunch”, which
is default in all Slots in Performance Mode, could be used as a volume reference.
EQ
The EQ (equalizer, often called “tone stack”) is an integral part of the stack section. It features four controls for the
different frequency bands: “Bass”, “Middle”, “Treble” and “Presence”. These controls are always present in Browse
and Performance Mode. Holding the EQ button will bring the EQ into focus. PROFILER Stage users should navigate
to page 3 of the amplifier module instead.
Basically, the equalizer in the PROFILER is a recreation of a generic, passive tone stack, but it is designed to have
more impact on the frequency bands. When all soft knobs are in the middle position, it does not change the sound,
so what you hear is the unaltered sound of the PROFILE.
A soft button allows you to set the position of the equalizer to either “Post” (after) or “Pre” (before) the amp module.
The EQ has a different impact on the sound of a distorting amp, depending on its position. In tube amps, it is
positioned between the preamp and the power amp. Most modern guitar amps with a master volume control perform
the distortion in the preamp; thus, the equalizer is positioned after the distorting circuit. Classic amps without master
volume control (such as Vox® AC-30), produce the distortion in their power amp. In this case, the equalizer is
positioned before the distorting circuit. However, setting the position according to the original amp is not mandatory,
since the authentic sound of the reference amp has already been captured, and therefore includes the original
equalizer setting.
