fabfilter Saturn has a feedback loop built in

Oh yeah! Forgot about that one. One of the best, IMO. Check out the preset FX/Destructiod bM for some real chaotic fun.

Old, abandoned, but free now and if you ignore small resolution it works as a charm (on Win at least) - Ohmicide

It has three bands max and for each you can set an own feedback. If the feedback is regarded good, compared to HW, I can not say, but at least, since you have three of them, you can achieve interesting results.

I landed on this page because I was looking for a gtr feedback plugin, after researching I realized I already had rift-feedback-lite (https://www.minimal.audio/products/rift-feedback-lite (https://www.minimal.audio/products/rift-feedback-lite)).
It's $15 though, but it REALLY WORKS. amazing. You can even set the notes thats supposed to resonate, ex. you play a C chord and bring a G feedback harmonic, that will sound pretty much like what happens naturally in the natural world.

Having said that, a solution that I haven't tried yet would be to setup a send channel with an amp plugin and an EQ just before. The EQ would chose the freq you want to bring out. Using automation u can : send your gtr to feedback channel gradually, emulating the build-up of feedback, gradually bring out different frequencies in your EQ, like fundamental + octave first then 5th, then 3rd...
A bit complicated setup, but would probably beat any Feedback emulation plugins

Wusik DL1 is perfect, except it sounds crackly for me and would be best sync free. Its Wikid! and free
