Chapter 8 Parameters Guide

In this chapter you will find detailed descriptions for each of the GT-10B’s effects and the parameters used to control them.

• The format used for parameter names is based on how the names are displayed when the screen is in list view.
• The sound that is input to each effect is called the “direct sound,” and the sound modified by the effect is called the “effect sound.”
• This effect sound is mono.
• This effect sound is output with two channels.

This is an effect that produces a long sustain by evening out
the volume level of the input signal. You can switch it to a
limiter to suppress only the sound peaks and prevent
distortion.

Explanation

COMP ON/OFF (Compressor ON/OFF)

Off, On Turns the COMP effect on/off.
Pressing [COMP] switches On and Off.

TYPE

Select the compressor type.
BOSS Comp Models the BOSS CS-3
D-Comp Models the MXR DynaComp.
BOSS Limitr This selects a stereo limiter.
Rack 160D Models the dbx 160x.
Vtg Rack U Models the UREI 1178.
Multi Band
This limiter lets you divide the input signal into
four separate bands—ultra low, low, high, and
ultra high frequency ranges—and apply differ-
ent settings to the low and high frequency rang-
es. You can set the frequencies separating each
band using the Xover f L, M, and H parameters.

The limiter is applied neither to the ultra low range,
which is critical to the bass’s sound, nor to the ultra
high range, which affects the nuance of the attack.

Natural
This compressor is configured using the same
frequency divisions as Multi Band, but with
simplified parameter settings.

Sustain *1

0–100
Adjusts the range (time) over which low-level
signals are boosted. Larger values will result in
longer sustain.

Attack

0–100
Adjusts the strength of the picking attack when
the strings are played. Higher values result in s
sharper attack, creating a more clearly defined
sound.

Threshold *2

0–100 When the input signal level exceeds this thresh-
old level, limiting will be applied.

Ratio *2

1:1–

∞

:1
This selects the compression ratio used with
signals in excess of the threshold level. Higher
values create a stronger compression effect.

Release *2

0–100
Adjusts the time from when the signal level
drops below the threshold until when limiting
is removed.

Lo Thres *3

0–100
In the Low Frequency Range, when the input
signal level exceeds this threshold level, limit-
ing will be applied.

Lo Ratio *3

1:1–

∞

:1
In the Low Frequency Range, this selects the
compression ratio used with signals in excess of
the threshold level. Higher values create a
stronger compression effect.

Hi Thres *3

0–100
In the High Frequency Range, when the input
signal level exceeds this threshold level, limit-
ing will be applied.

Hi Ratio *3

1:1–

∞

:1
In the High Frequency Range, this selects the
compression ratio used with signals in excess of
the threshold level. Higher values create a
stronger compression effect.

Xover f L (Crossover Frequency Low) *3

32Hz–315Hz This sets the frequency dividing the ultra low-
and low-frequency ranges.

Xover f M (Crossover Frequency Middle) *3

100Hz–4.00kHz This sets the frequency dividing the low- and
high-frequency ranges.
