What Acoustic Feedback does
The plugin models the interaction between a guitar and the amplifier and room around it, which the developer identifies as the hard part of guitar amplifier simulation. Input is not limited to guitar: the developer suggests trying a synthesizer, a violin or a grand piano.
Key features
- Feedback amount and tolerance. A Feedback knob sets how far the sound moves from moderate, subtle feedback to rampant, wild feedback, and a Tolerance switch sets how sensitive the feedback is to the input.
- Physical modeling of feedback. The developer describes the feedback as a realistic simulation of physical guitar feedback rather than a generic distortion.
- Responsive bends and vibrato. Vibratos, bends, slides and tremolos are followed by the feedback, which the developer says responds fully to playing technique.
- Sustain fade. Single notes can be kept ringing for a little longer, or the sustained feedback can be faded out gently.
- Bundled White amp. A stripped-down White amp from Vintage Amp Room is included, with only the Master Volume and Mic position available.
