 EQ pop-up menu: Choose one of the four EQ models. The choices are:
British 1, British 2, American, and Modern EQ.
 Amp–Speaker Link button: Links the Amp and Speaker menus so that when you
change the amp model, the speaker associated with that amp is loaded
automatically.
 Amp–EQ Link button: Links the Amp and EQ menus so that when you change the
amp model, the EQ model associated with that amp is loaded automatically.
Each amp model has a speaker and EQ model associated with it. Together, the amp,
speaker, and EQ combined recreate a well-known guitar sound. However, you can
freely combine any speaker or EQ model with any amp by turning off the two Link
buttons.
 Gain knob: Sets the amount of pre-amplification applied to the input signal. This
control has different effects, dependent on which Amp model is selected. For
example, when using the British Clean amp model, the maximum Gain setting
produces a powerful crunch sound. When using the British Gain or Modern Gain
amps, the same Gain setting produces heavy distortion, suitable for lead solos.
 Bass, Mids, and Treble knobs: Adjusts the frequency ranges of the EQ models, similar
to the tone knobs on a hardware guitar amplifier.
 Presence knob: Adjusts the high frequency range. The Presence parameter affects
only the output (Master) stage of Guitar Amp Pro.
