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.
Dynamic button: Emulates the sound of a dynamic cardioid microphone. This microphone type sounds brighter and more cutting than the Condenser model. At the same time, the lower-mid frequency range is less pronounced, making this model more suitable for miking rock guitar tones.
Tip: Combining both microphone types can sound quite interesting. Duplicate the guitar track, and insert Guitar Amp Pro as an insert effect on both tracks. Select different microphone types in each Guitar Amp Pro instance, while retaining identical settings for all other parameters, and mix the track signal levels. You can also choose to vary any other parameters.
