also..if he has the wrong things checked in his soundcard options,
like monitoring his line in. He could be getting the feedback from that.
And because its a cheapo soundcard the latency is just enough that
instead of traditional feedback.. it will sounds more like a delay effect
and start quiet and get louder.
If the wrong things are checked off, the loop might not even be caused
by the guitar but rather you created an electronic "loop" inside of the computer.
