DRIVE
The DRIVE amp type provides a selection of distortion
sounds that simulate the tonal character of various high-
gain tube amplifiers. From mildly overdriven crunch to
heavy distortion suitable for hard rock, heavy metal, or
hardcore styles, this model offers a wide range of sonic
capabilities.
1 AMP TYPE
Six amplifier types are provided. Types 1 and 2 feature
relatively mild distortion that allows picking nuances to
come through naturally. Types 3 and 4 have more
pronounced overtones, resulting in a fat, soft tone. Types 5
and 6 deliver wilder, aggressive distortion with a tight
attack. The even-numbered amp types have greater
presence and range than the odd-numbered types.
2 GAIN
Adjusts the input level applied to the preamp stage. Rotate
clockwise to increase the amount of distortion produced.
3 MASTER
Adjusts the output level from the preamp stage.
4 TREBLE/MIDDLE/BASS
These three controls adjust the amplifier’s tonal response
in the high, middle, and low frequency ranges.
5 PRESENCE
Can be adjusted to emphasize the high frequencies and
overtones.
6 OUTPUT
Adjusts the final output level.
LEAD
The LEAD amp type simulates a high-gain tube amp that is
rich in overtones. It is ideally suited to playing lead guitar
lines that will project well in an ensemble, but it can also be
set up for crisp accompaniment tones as well.
1 High/Low
Selects the amp output type. The [High] setting simulates a
high-output amp, and allows the creation of more distorted
tones.
2 GAIN
Adjusts the input level applied to the preamp stage. Rotate
clockwise to increase the amount of distortion produced.
3 MASTER
Adjusts the output level from the preamp stage.
4 TREBLE/MIDDLE/BASS
These three controls adjust the amplifier’s tonal response
in the high, middle, and low frequency ranges.
5 PRESENCE
Used to emphasize the high frequencies and overtones.
6 OUTPUT
Adjusts the final output level.
HINT
Using the GAIN, MASTER, and OUTPUT Controls
The tonal character of the DRIVE and LEAD amp
types can be adjusted over a wide range via the
GAIN, MASTER, and OUTPUT controls. GAIN
adjusts the level of the signal applied to the preamp
stage, affecting the amount of distortion produced.
MASTER adjusts the output level from the preamp
stage that is then fed to power amp stage. The GAIN
and MASTER control settings have a large effect on
the final sound, and the MASTER control may need
to be turned up fairly high in order to drive the power
stage sufficiently for optimum tone. The OUTPUT
control adjusts the final output level from the amp
model without affecting the distortion or tone, and is
useful for adjusting the guitar’s volume without
changing any other aspects of the sound.
