Legacy Guitar Amp Pro in Logic Pro for Mac
Guitar Amp Pro simulates the sound of popular guitar amplifiers and the speakers used with them. You can process guitar signals directly, reproducing the sound of your guitar through a number of high-quality guitar amplification systems. Guitar Amp Pro can also be used for experimental sound design and processing. You can use it with other instruments, applying the sonic character of a guitar amp to a trumpet or vocal part, for example.

An amplifier “model” consists of an amplifier, speaker cabinet, EQ type, and microphone type. You can create your own hybrids of different amplifiers, cabinets, and so on—using the pop-up menus at the top center of the interface. You choose the microphone position and type in the yellow areas to the left and right. Guitar Amp Pro also emulates classic guitar amplifier effects, including reverb, vibrato, and tremolo.
You can use the Settings pop-up menu to save your new hybrid amp combos as setting files, which also include any parameter changes you may have made.
The Guitar Amp Pro window is organized into several parameter sections.
Amp section: The model parameters at the top are used to choose the type of amp, EQ model, and speaker. The knobs in the V-shaped section are used to set tone, gain, and level. See Guitar Amp Pro amplifier models, Guitar Amp Pro cabinet models, and Guitar Amp Pro EQ.
Effects section: Provides parameters to control the built‑in tremolo, vibrato, and reverb effects. See Guitar Amp Pro effects.
Microphone Position and Type sections: These sections enable you to set the position and type of the microphone. See Guitar Amp Pro mic parameters.
Output slider: The Output slider is found at the bottom, below the Effects section. It serves as the final level control for Guitar Amp Pro and can be thought of as a “behind the speaker” volume control that is used to set the level fed to the ensuing plug-in slots on the channel strip or to Output channel strips.
Note: This parameter is different from the Master control, which serves the dual purpose of sound design as well as controlling the level of the Amp section.
