Amp Designer amplier controls
The amp parameters include controls for the input gain, presence, and master output. The Gain
knob is located to the left in the knobs section, the Presence and Master knobs are to the right,
and the Output parameter is at the lower-right edge of the interface.

Amplier parameters
•
Gain knob: Rotate to set the amount of pre-amplication applied to the input signal. This
control aects specic amp models in dierent ways. For example, when you use the British
Amp, the maximum gain setting produces a powerful crunch sound. When you use the
Vintage British Head or Modern British Head, the same gain setting produces heavy distortion,
suitable for lead solos.
•
Presence knob: Rotate to adjust the ultra-high frequency range—above the range of the Treble
control. The Presence parameter aects only the output (Master) stage.
•
Master knob: Rotate to set the output volume of the amplier signal sent to the cabinet. For
tube ampliers, increasing the Master level typically produces a compressed and saturated
sound, resulting in a more distorted and louder signal.
WARNING: Because high Master knob settings can produce an extremely loud output that
can damage your speakers or hearing, start with a low Master knob setting and then slowly
increase it.
•
Output slider or eld: Drag to set the nal output level of Amp Designer.
Note: The slider is replaced with a eld in the small interface.
