64. VS Overdrive
This is an overdrive that provides heavy distortion.
● Drive (0~127)—Degree of distortion. Also changes the vol-
ume.
● Tone (0~127)—Sound quality of the Overdrive effect.
● Amplifier Sw (Off, On)—Turns the Amp Simulator on/off.
● Amplifier Type (Small, Built-In, 2-Stack, 3-Stack)—Type
of guitar amp. SMALL: small amp, BUILT-IN: single-unit
type amp, 2-STACK: large double stack amp, 3-STACK: large
triple stack amp.
● EQ Low Gain (–15dB~0~15dB)—Gain of the low fre-
quency range.
● EQ High Gain (-15dB~0~15dB)—Gain of the high fre-
quency range.
● Panpot (L64~0~63R)—Stereo location of the output
sound. This is a mono effect that combines incoming sig-
nals. You can, however, place the processed signal any-
where between the left and right channels.
● Level (0~127)—Output level.
65. VS Distortion
Produces a more intense distortion than the above. The
parameters are the same as for “64. VS Overdrive”.
66. GT Amp Simul
This is an effect that simulates the sound of a guitar amplifier.
● Pre Amp Sw (Off, On)—Turns the amp switch on/off.
● Pre Amp Type (JC-120, Clean Twin, Match Drive, BG
Lead, MS1959I, MS1959II, MS1959I+II, Sldn Lead, Metal
5150, Metal Lead, OD-1, OD-2 Turbo, Distortion, Fuzz)—
Type of guitar amp
● Pre Amp Volume (0~127)—Volume and amount of distor-
tion of the amp.
● Pre Amp Master (0~127)—Volume of the entire pre-amp.
● Pre Amp Gain (Low, Middle, High)—Amount of pre-amp
distortion.
● Pre Amp Bass (0~127)
● Pre Amp Middle (0~127)
● Pre Amp Treble (0~127)—Tone of the bass/mid/treble fre-
quency range.
*Middle cannot be set if “Match Drive” is selected as the Pre
Amp Type.
● Pre Amp Presence (0~127 [Match Drive: –127~0])—
Tone for the ultra-high frequency range.
● Pre Amp Bright (Off, On)—Turning this “On” produces a
sharper and brighter sound.
*This parameter applies to the “JC-120,” “Clean Twin,” and
“BG Lead” Pre Amp Types.
● Speaker Sw (Off, On)—Determines whether the signal
passes through the speaker (ON), or not (OFF).
● Speaker Type (Small 1, Small 2, Middle, JC-120, Built-In
1, Built-In 2, Built-In 3, Built-In 4, Built-In 5, BG Stack 1,
BG Stack 2, MS Stack 1, MS Stack 2, Metal Stack, 2-Stack,
3-Stack)—Select the type of speaker. The specifications of
each type are as follows. The speaker column indicates the
diameter of each speaker unit (in inches) and the number
of units.
● Mic Setting (1, 2, 3)—Adjusts the location of the mic
that’s capturing the sound of the speaker. This can be
adjusted in three steps, from 1 to 3, with the mic becoming
more distant as the value increases.
● Mic Level (0~127)—Volume of the microphone.
● Direct Level (0~127)—Volume of the direct sound.
● Panpot (L64~0~63R)—Stereo location of the output
sound. This is a mono effect that combines incoming sig-
nals. You can, however, place the processed signal any-
where between the left and right channels.
● Level (0~127)—Output level.
67. Gate
Cuts the reverb’s decay according to the volume of the sound
sent into the effect. Use this when you want to create an arti-
ficial-sounding decrease in the reverb’s decay.
● Threshold (0~127)—Volume level at which the gate begins
to close
● Mode (Gate, Duck)—Type of gate. GATE: The gate will close
when the volume of the original sound decreases, cutting
the original sound. DUCK (Ducking): The gate will close
when the volume of the original sound increases, cutting
the original sound.
● Attack (0~127)—Adjusts the time it takes for the gate to
fully open after being triggered.
● Hold (0~127)—Adjusts the time it takes for the gate to
start closing after the source sound falls beneath the
Threshold.
● Release (0~127)—Adjusts the time it takes the gate to
fully close after the hold time.
● Balance (D100:0W, D50:50W, D0:100W)—Volume bal-
ance between the direct (D) and the effect sound (W).
● Level (0~127)—Output level.
