For Guitarists: Outstanding Amp Simulation & Effects
The Volume Parameter
A "Volume" parameter which affects the overall volume of
the setup is located at the top of the parameter list. This parame-
ter is most useful for matching the levels of the setups to suit
your musical needs. You might, for example, want all of your gui-
tar setups to have about the same level, or you might want cer-
tain effects you've set up for solos to have a higher level than the
rest. Parameters such as preamp drive and EQ also affect the
subjective level of the guitar sound, and the Volume parameter is
a convenient way to compensate for such variations.

The Preamp Block
Depending on the selected setup, you'll see one or three
preamp parameters below the "Volume" parameter. In some set-
ups only the "Drive" parameter will be available, while in others
you will have "Drive", "EQ LowGain" and "EQ Hi Gain". Here's
what the preamp parameters do:

parameters
Drive In guitarist-friendly terms, this parameter is similar to
the "gain" or "pre-gain" control on an amplifier that
has both gain and master volume controls. Higher
"Drive" values (range: 000 ... 127) produce more over-
drive (distortion).
