Guitar Amp Pro effects in MainStage
The effects parameters include Tremolo, Vibrato, and Reverb, which emulate the processors found on many amplifiers.
You can use the pop-up menu to choose either Tremolo, which modulates the amplitude or volume of the sound, or Vibrato, which modulates the pitch.
Reverb can be added to either of these effects, or used independently.
To use or adjust an effect, you must first enable it by clicking the corresponding On button to the left. The On button is red when active.
Note: The Effects section is placed before the Presence and Master controls in the signal flow, and receives the preamplified, pre-Master signal.
Tremolo and vibrato parameters
On/off button: Turn the tremolo/vibrato effect on or off.
FX pop-up menu: Choose either Tremolo or Vibrato.
Depth knob: Set the intensity of the modulation.
Speed knob: Set the speed of the modulation in hertz. Lower settings produce a smooth and floating sound, while higher settings produce a rotor-like effect.
Sync button: Turn on to synchronize the modulation speed with the project tempo. You can adjust the Speed knob to select bar, beat, and musical note values (including triplet and dotted notes). When the Sync button is turned off, the modulation speed can be set to any available value with the Speed knob.
Reverb parameters
On/off button: Turn the reverb effect on or off.
Reverb pop-up menu: Choose one of the three types of spring reverb.
Level knob: Rotate to set the amount of reverb applied to the pre-amplified amp signal.
