Here's my solutions.......

1.) trim a small piece of wood that will fit in the hole where the screw goes, glue it in, and just screw the screw back into it after the glue dries....this method worked on my Ibanez which did the same thing.

2.) probably something to do with a setting in the window's mixer....or the mixer that came with the soundcard if it came with one....try other settings.

3.) Opposite styles can work..The other guitarist in my band and I have completely different styles, tones, ect......I play a Music Man through a Marshall while he plays a Gibson through a Mesa Boogie..He's more bluesy sounding and a little sloppy while I am a little more technical and more precise. Opposite's, but it works for us.....He has a little more gain than me, but not really much. You'll either need to back off on your gain, or increase his a bit...

4.) You might want to see a doctor about that burning.....
