Bass Amp Model Tone Controls:
Bass – bass tone control.
Lo Mid – low-mid tone control.
Hi Mid – high-mid tone control.
Treble – treble tone control.
Drive – controls how hard you’re driving the input of the chosen Amp Model, and
just like the input volume control on a non-master volume guitar amp, higher settings
give you more “dirt”.
Vol – controls the relative volume level of the current Tone; you can use this to balance
levels between various tones, but in general, you should set this as high as possible for
the best signal-to-noise ratio.
