My blog post on the topic, with two clips, one with Acoustic Feedback, and the same clip rendered without it. I used Studio Devil's Amp Modeler Pro rather than one of Softube's _______ Amp Room plugins because I wanted to show that it's platform-neutral and works well with anything.
Anyway, have a read, have a listen, and let me know what you think.
I'll add a bit here because I think it's relevant, came out in another discussion thread on the review at GAM:
Please listen to both clips, not just the one where it's active. I included both clips because I wanted to give you the best sense of its effects, and also let you see that when sustain and feedback aren't appropriate, it doesn't muck up the playing; when I'm just noodling, it doesn't randomly go into feedback or anything like that, it stays unobtrusively dormant until feedback would be appropriate. That is a result of adjusting the three controls, and you'll need to do that differently depending on your guitar and your amp model. After all it can't tell the difference between a clean Fender model, a cranked Plexi model, or a Triple Rec model, but you obviously wouldn't want the same level of feedback for each. Not a one-size-fits-all plugin but then you wouldn't expect it to be, and they give you all of the level of control necessary to adjust it to the appropriate style of feedback for whatever you're using.
