simulating guitar-type feedback...

I use amp sims and I get feedback when my monitors are a little on the loud side.
You're not using headphones are you?

you can use monitors or headphones, they don't have to be loud, just close to the mic. Then, run it through an amp sim

It was an interesting link  - but it says:  "...Acoustic Feedback Deluxe is at the present only available for Pro Tools HD and VENUE as a TDM plug-in..."

AH Nice - Thanks F@ker.

For those who may wonder what his second post means - the regular version of Acoustic Feedback is compatible with all VST hosts.  That's the one on the new link.  It's the Deluxe version earlier posted which is currently only for Pro Tools and Venue.

Neat.

I use a sansamp for direct recording into nearfields. Getting real, genuine feedback is no problem at all, even at low volumes, so long as I use enough gain.

Guitar feedback is not the same thing as the feedback you get by sticking a mic in front of a speaker. The feedback note on a guitar is always an octave higher than the fretted note. Mic feedback is an uncontrollable BLEEEEEEE at whatever the frequency happens to match the distance of the mic to the speakers and resonate. :)

Guitar feedback occurs when the string of the guitar goes into sympathetic resonance, driven by the speaker, and picked up by the pickup. This is why you can bend and vibrato a feedback sound by bending the string while the guitar is feeding back.

The key is you need to find the resonant notes on the guitar, and hold that note perfectly clean with a moderate to high gain setup. The volume has to be up quite a bit if you're not using a lot of gain. An easy one is the 12th fret on the 3rd string.

 If you want to emulate the sound, then the easiest way is to crossfade the note with an octave harmonic (i.e. the harmonic 12 frets up from your note) in Sonar. Record the guitar part first, then record the harmonic in the second pass, finally editing it in by a simple cross fade.

Yeah, that softube plug is interesting but what I found when I demoed it was it changed the original sound too much. Maybe they have fixed this (it's been quite some time since I tried it.)

I haven't used Slayer for a while, but used to get convincing feedback from it.

This might sound stupid, but what I sometimes use for feedback is a flute sound.  I got the idea from some professional MIDI's that I purchased that use flute for feedback.   If you take that concept a step further and stick the flute sound behind a real guitar, with the proper mix, reverb level, cross-fades, it can actually sound believable.   You have to tweak with it to get it right but it beats the alternative of the wife hitting you with a frying pan.

You can adjust the wet/dry on it, or even use it on a send.

I didn't think about that (facepalm)

But I have never tried to see if it will feedback on a recorded trk

 
As the "feedback" sound (actually sympathetic resonance of the string at the note you are playing  that rapidly builds in volume leading to the amp/preamp saturating and massive compression) comes entirely from the guitar string and is nothing to do with any mics in front of a guitar speaker at all, if you can get guitar feedback from your monitors it will record OK.
 
You do need speakers to provide the sound for the guitar to resonate to. A spare pair of headphones close to the neck may even do the trick (haven't tried).
 
By the way - be careful setting up guitar feedback while monitoring on headphones - it can get very (damagingly) loud without you really noticing until it stops - and the ringing in the ears noise starts.
