Using Guitar Amp Pro’s Tremolo and Vibrato Effects
Tremolo and vibrato are controlled by an On button, the FX pop-up menu, the Depth
and Speed knobs, and the Sync button in the Effects section. Tremolo modulates the
amplitude or volume of the sound, and vibrato modulates the pitch.
• FX pop-up menu: You can choose either Tremolo or Vibrato.
• Depth knob: Sets the intensity of the modulation.
• Speed knob: Sets 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: When the Sync button is turned on, the modulation speed is synchronized
to 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.
Using Guitar Amp Pro’s Reverb Effect
Reverb is controlled by an On button, the Reverb pop-up menu, and a Level knob in the
Reverb section near the bottom. Reverb can be added to either the Tremolo or Vibrato
effect, or used independently.
• Reverb pop-up menu: Choose one of the three types of spring reverb.
• Level knob: Sets the amount of reverb applied to the pre-amplified amp signal.
Setting Guitar Amp Pro Microphone Parameters
After choosing a speaker cabinet from the Speaker menu, you can set the type of
microphone you want to be emulated, and where the microphone is placed in relation
to the speaker. The Microphone Position parameters are available in the yellow area to
the left, and the Microphone Type parameters in the yellow area to the right.
Microphone Position Parameters
• Centered button: Places the microphone in the center of the speaker cone, also called
on-axis. This placement produces a fuller, more powerful sound, suitable for blues or
jazz guitar tones.
• Off-Center button: Places the microphone on the edge of the speaker, also referred to
as off-axis. This placement produces a tone that is brighter and sharper, but also
thinner—suitable for cutting rock or R & B guitar parts.
When you select either button, the graphic speaker display reflects your choice.
Microphone Type Parameters
• Condenser button: Emulates the sound of a studio condenser microphone. The sound
of condenser microphones is fine, transparent, and well-balanced.
