Pb: Pedal Bend; 2Ce: 2X2 Chorus - Boss GT-6B Owner's Manual

Chapter 4 The Effects Explained
Mono:
This mode is for the input of individual notes.
Select this setting when you want to obtain a pedal bend
effect using an external expression pedal.
* Because of the need to analyze the pitch, chords (two or more
sounds played simultaneously) cannot be played.
Pitch
Adjusts the amount of pitch shift (the amount the pitch
changes) in semitone steps.
Fine
Makes fine adjustments to the pitch shift.
* "100" units of change in Fine is equivalent to "1" full change
in pitch.
PreDly (Pre Delay)
Adjusts the time from when the direct sound is played until
the pitch shifted sounds are produced. Normally, you can
leave this set at "0 ms."
* When set to BPM, the value of each parameter is set according
to the value of the Master BPM (p. 44) specified for each patch.
This makes it easy to achieve effect sound settings that match
the tempo of the song (synchronizing the cycle to one-half or
one-fourth of the BPM when the set cycle rate is increased).
When setting to the BPM, press PARAMETER [
display the Master BPM settings screen.
Feedback
This adjusts the feedback amount of the pitch shift sound.
Increasing the Feedback level produces an effect whereby the
sound seems to rise and fall with the reverberations.
* Only PS1 can be selected when this is set to 2-Mono or 2-Stereo.
Level
This adjusts the volume of the pitch shift sound.
Direct Level
Adjusts the volume of the direct sound.

PB: Pedal Bend

This lets you use the pedal to get a pitch bend effect. The GT-
6B's expression pedal automatically switches to the pedal
bend function when PB is selected.

This sets the pitch at the point where the expression pedal is
all the way down.
Pdl Position (Pedal Position)
This adjusts the pedal position for pedal bend.
Effect Level
This adjusts the volume of the pitch bend sound.

Xover f (Crossover frequency)
This parameter sets the frequency at which the direct sound
is divided into low- and high-frequency ranges.
Lo Rate (Low Rate)
Adjusts the rate of the chorus effect in the lower range.
* When set to BPM, the value of each parameter is set according
to the value of the Master BPM (p. 44) specified for each patch.
This makes it easy to achieve effect sound settings that match
the tempo of the song (synchronizing the cycle to one-half or
one-fourth of the BPM when the set cycle rate is increased).
When setting to the BPM, press PARAMETER [
display the Master BPM settings screen.
Lo Depth (Low Depth)
Adjusts the depth of the chorus effect for the lower range. If
you wish to use this as a doubling effect, use a setting of "0."
