Amp, Cab & Mic Models

• Knob 1: Changes the Bias of the power tubes. Set to minimum to achieve a
very “cold” Class AB biasing. At maximum the amp is operating in Class A.
• Knob 2: The Bias Excursion determines how the power amp tubes’ voicing
reacts when they are pushed hard. Set low for a tighter feel. Set high for
more tube compression. This parameter is highly reactive with the DRIVE &
MASTER settings.
• Knob 3: Has no function on this page.
Amp Edit - Page 4
Here you’ll nd Microphone and Speaker Cabinet options.
Page 4 of the AMP:EDIT Screen (appears as Page 2 for Preamp Models)
NOTE: If you selected “No Cab” for your Cab Model, these Mic and Early Reections settings
will perform no function since no Speaker, Mic or Early Reections processing is applied.
• Knob 1: Sets the amount of “early reections.” Higher values add more
reective room sound to your Amp tone.
• Knob 2: Applies low frequency attenuation - helpful to tighten up the low
end of your tone.
• Knob 3: Selects the Mic type (see the Mic Model table on page 6•5).
Press the HOME button, or double-press the ENTER button to exit the AMP:EDIT screen
when done. Be sure to save your Preset to retain customized Amp Model settings.
