Control it from the strings
Leave a note ringing and feedback blooms. Keep riffing and it ducks under your playing. Mute the strings with your palm and it dies, the same move as on stage.
Guitar feedback you can summon on demand. It listens to what you play and synthesises the feedback from scratch: singing sustain without the amp, the volume or the room.
One guitar phrase, three stages: raw DI, through an amp, then with Feedback Emulator in front of that amp.
Feedback, Texture, Envelope and Output run the everyday view: which harmonic sings, how it growls and drifts, how fast it blooms and how loud it sits. The ADV toggle, switched on here, adds the trigger controls and output trim.

Leave a note ringing and feedback blooms. Keep riffing and it ducks under your playing. Mute the strings with your palm and it dies, the same move as on stage.
Four harmonic modes pick what sings: natural overtones, a thick fundamental drone, the classic octave squeal or piercing upper harmonics.
The character knobs. Growl adds snarl that thickens as the feedback swells, Wander lets a long note drift and breathe. No two sustains repeat.
Free for personal and commercial use. No trial, no upsell. The first plugin from veles.audio.
Feedback Emulator is free, forever. Drop it on a DI track before the amp sim, pick a preset and let a note ring.
