MID CUT
You can scoop out harsh midrange by set-
ting the FREQUENCY slider AROUND
12:00 with the CONTOUR Level cut to taste
below the center detent. Often the desired
mid-cut will fall into the same frequency
range as potential microphone feedback.
You can also cut midrange (pickup only) by
boosting the BASS and TREBLE sliders to
realize an "implied" mid-cut at 800 Hz.
FINGERSTYLE
This setting will add fullness to the bass and
definition to the treble.

WHAT IS PHASE?
Phase is the relationship between two signals or sound waves originating from the
same instrument.
For our purposes, phase relationships are expressed as being either "in phase" or
"out of phase".
In phase
tends to enhance, while
out of phase
tends to suppress
the natural characteristics and acoustic tendencies of an instrument. A simple
way to determine the quality of phase (in or out) of two sounds is to compare
phase switch settings at low volumes.
IN PHASE
In phase
is when the wave
forms of two sounds
originating from the same
instrument are similarly
aligned in time. Similar phase
is like looking at yourself in a
mirror: your reflection directly
follows your movement.
OUT OF PHASE
Out of phase
is when the
wave forms of two sounds
originating from the same
instrument are aligned such
that the upper peak of one
wave occurs at the same
moment in time as the lower
peak of the other.
Out of
phase
is like looking at
yourself in a live video
monitor; the image you see is
similar, but the perspective is
shifted.
When you move to the right,
the image appears to move to your left.
