Acoustic Feedback: Guitar Feedback Simulator Plugin by Softube

The core of Acoustic Feedback is a simple two-control interface. The Feedback knob sets how much feedback is produced, from subtle sustain to wild, uncontrolled howl. The Tolerance switch sets how sensitive the plugin is to the incoming signal, which determines how easily feedback starts.

Because the plugin responds to vibrato, bends, slides and tremolo, you can shape feedback through your playing rather than through automation alone. Softube says the plugin is designed to reproduce the interaction between a guitar and a loud amplifier in a room, something that is difficult to achieve with standard amp simulators.

Acoustic Feedback supports MIDI foot controls, which makes it practical for live-style performance in a studio session. It is also useful for experimenting beyond guitar. Softube suggests trying it with a synthesizer, a violin or a piano.

The bundled White amp from Vintage Amp Room is a stripped-down version. Only the Master Volume and Mic position controls are functional; the other controls are not available. The plugin is best suited to producers who want feedback textures for noise rock, experimental or ambient work, or single-note sustain effects.
