Hi

Yer I had the same kind of proplem.

i often wondered why peop;le mike there amps through computers? and thats the reason because unless you have a dedicated computer for sound only there is allsorts of weard and wonderfuly things going on in the background.

Say that I managed to improve mine a bit by running my guitar through a Di box with The XLR output on the box.

This was a slight improvement if I want to record I mike my amp up and record that way, it is also much close to the true sound you are playing.

hope this helps.
