Sh (Sound Hold); Sdd (Sub Delay); Eq (Equalizer) - Boss gt-8 Owner's Manual

SH (Sound Hold)

You can have sound played on the guitar be held
continuously. This effect allows you to perform the melody
in the upper registers while holding a note in the lower
registers.
* This function will not work properly when two or more notes
are played simultaneously.
Parameter/
Explanation
Range
Hold
Off, On Switches the hold sound on and off.
Normally, this is assigned to the CTL pedal.
Rise Time
Adjusts how rapidly the Sound Hold sound
0–100
is produced.
Effect Level
0–120 Adjusts the volume of the hold sound.

SDD (Sub Delay)

This is a delay with the maximum delay time of 400 ms. This
effect is useful for making the sound fatter.
Parameter/
Explanation
Range
Delay Time
0 ms–400 ms,
Adjusts the delay time.
BPM –BPM
* When set to BPM, the value of each parameter will be set according to
the value of the Master BPM (p. 51) specified for each patch. This makes
it easier to achieve effect sound settings that match the tempo of the
song (synchronizing the time to twice or four times the time length of
the BPM when the set time is increased).
When setting to BPM, press PARAMETER [
display the Master BPM settings screen.
Feedback
Adjusts the volume that is returned to the
0–100
input.
Feedback refers to returning the delayed signal back into the input
of the delay. Higher settings will result in more delay repeats.
Effect Level
0–120 Adjusts the volume of delay sound.
Chapter 4 Introduction to Effects and Parameters

EQ (Equalizer)

Adjusts the tonal quality. A parametric type equalizer is used
for the upper and lower midrange.
Parameter/
Range
On/Off
Off, On
Low Cut (Low Cut Filter)
Flat, 55 Hz–800 Hz
This lets you cut the low-end component below the set frequency to
create a clear, distinct low end, thereby bringing out the high end of
the effect. When "Flat" is selected, the low cut filter will have no ef-
fect.
Low EQ
-20 dB–+20 dB
Low-Middle Frequency
20.0 Hz–10.0 kHz
Low-Middle Q
0.5–16
Higher values will narrow the area.
Low-Middle EQ
-20 dB–+20 dB
High-Middle Frequency
20.0 Hz–10.0 kHz
High-Middle Q
] several times to
0.5–16
Higher values will narrow the area.
High-Middle EQ
-20 dB–+20 dB
High EQ
-20 dB–+20 dB
High Cut (High Cut Filter)
700 Hz–11.0kHz, Flat
This allows you to get a mild effect sound by cutting the high-end
component above the set frequency. When "Flat" is selected, the
high cut filter will have no effect.
Level
-20 dB–+20 dB
Explanation
Turns the EQ on/off.
This sets the frequency at which the low cut
filter begins to take effect.
Adjusts the low frequency range tone.
Specify the center of the frequency range
that will be adjusted by the "Lo-Middle
EQ."
Adjusts the width of the area affected by the
EQ centered at the "Lo-Middle frequency."
Higher values will narrow the area.
Adjusts the low-middle frequency range
tone.
Specify the center of the frequency range
that will be adjusted by the "Hi-MidDle
EQ."
Adjusts the width of the area affected by the
EQ centered at the "Hi-Middle frequency."
Higher values will narrow the area.
Adjusts the high-middle frequency range
tone.
Adjusts the high frequency range tone.
This sets the frequency at which the high cut
filter begins to take effect.
Adjusts the volume after the equalizer.
