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.
