LOW GAIN Function
The GAIN parameter determines the gain value in the distortion stage.
The DISTORTION TYPE parameter allows you to select between four different distortion
types - Solid State, Pentode, Triode A and Triode B. The Solid State setting provides the
hardest clipping, while the Pentode type provides a softer clipping and the Triode A and B
types provide the softest clipping. Triode A emulates a triode tube operating in Class A,
with non-symmetrical clipping - and therefore more even harmonics produced. Triode B
emulates a pair of triode tubes operating in Class B, with symmetrical clipping. The
differences between these types are most pronounced at moderate gain settings of about
30dB or less, where Triode B produces the least amount of upper harmonics.
The post BASS LEVEL parameter adjusts the amount of low frequency information at the
output of each preset. This parameter is also accessible from the "Post EQ (Expert)"
function. (In the Post EQ function, the center frequency and bandwidth of this EQ section
are also adjustable.)
The post MID LEVEL parameter adjusts the amount of mid frequency information at the
output of each preset. This parameter is also accessible from the "Post EQ (Expert)"
function. (In the Post EQ function, the center frequency and bandwidth of this EQ section
are also adjustable.)
The post TREBLE LEVEL parameter adjusts the amount of high frequency information at
the output of each preset. This parameter is also accessible from the "Post EQ (Expert)"
function. (In the Post EQ function, the center frequency and bandwidth of this EQ section
are also adjustable.)
The post PRESENCE LEVEL parameter also adjusts the amount of high frequency
information at the output of each preset. This parameter is also accessible from the "Post
EQ (Expert)" function. (In the Post EQ configuration, the center frequency and bandwidth
of this EQ section are also adjustable.)
The LOW GAIN function is only accessible in configurations which display "L-GAIN" in the configuration title.
The preamp stage in these configurations provides four distortion types, and can also be used for clean tones.
The PARAMETER SELECT control will allow you to access these Low Gain parameters:
