all about feedback techniques (local backup made)
Several guitarists have been working on a circuit, I suggest you compare notes.

One sign of a real rock guitar rig, rather than an, amateur, corner-cutting, fake rock guitar rig, is feedback. I like feedback because it's a sign of volume and power, and the idea of feedback is interesting and suggestive.
I tried holding my guitar strings next to the speaker cabinet to see if the pressure waves would alter the dynamic envelope of plucked notes, but I couldn't hear any such effect. Feedback, however, is an obvious effect of holding the guitar next to a real, cranked amp.
You can get feedback at low volumes using lots of preamp distortion.

jonnra, below, is working on a sustainer circuit.
Michael,
>Here is a site that has some samples of sustainer technology. It is very similar to the music I am currently making.
driver-pickup sustainer circuits and samples
Run through 2 amps. One, a sweet, warm, rather clean amp, and the other, a balls-to-the-wall Marshall on 11. Stand in front of the Marshall so the guitar sings/screams on almost whatever you play. Mic only the clean amp, away from the Marshall. It is a cool effect. The guitar behaves totally differently and you get some serious sustain and singing tone without ridiculous distortion.

>There *are* ways to get feedback at extremely low volumes. My
personal formula for that involves a semi-hollowbody with sensitive
pickups, a Boss compressor, my 250H set to one of the hotter
Johnson or Matchless presets, and my stereo Peavey 4x10. With
some patches, I can get the setup do the Santana "infinite note"
thing at slightly louder than conversational volume.

Get physical feedback to the strings from one amp, but mic a different amp
