High Gain Function - Rocktron VOODU Valve User Manual

The PARAMETER SELECT control will allow you to access these High Gain parameters:
TUBE GAIN The TUBE GAIN parameter sets the amount of drive at the input of the
tube stage.
GAIN The GAIN parameter determines the gain value in the distortion stage.
VARIAC ADJUST The VARIAC ADJUST parameter adjusts the level at which the preamp
stage in the Voodu Valve™ begins to distort. A Variac is a voltage-
attenuating device that plugs into an AC wall outlet and adjusts the
voltage level to any device which is plugged into it. For years, many
guitarists have plugged their amplifier heads into a Variac and reduced
the voltage coming into the amplifier from the AC wall outlet. This
allows the amplifier tubes to reach saturation at a lower input level and
increases the gain produced. The VARIAC ADJUST parameter
operates in a similar manner as a conventional Variac - where lowering
the parameter value lowers the level at which saturation will take place.
BASS LVL The post BASS LEVEL parameter adjusts the amount of low frequency
information at the output of each preset. This parameter is also acces-
sible from the "Post EQ (Expert)" function. (In the Post EQ function,
the center frequency and bandwidth of this EQ section are also adjust-
able.)
MID LVL The post MID LEVEL parameter adjusts the amount of mid frequency
information at the output of each preset. This parameter is also acces-
sible from the "Post EQ (Expert)" function. (In the Post EQ function,
the center frequency and bandwidth of this EQ section are also adjust-
able.)
TREBLE LVL 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.)
PRESENCE LVL 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
function, the center frequency and bandwidth of this EQ section are also
adjustable.)
