A lot of people say that the GT10 does not sound decent through a guitar amp. I thought that I would put a track together using the GT10 into a Marshall TSL and then micing it and recording it. The guitars used were a Strat in the intro and a Tokai Love Rock for the "harder" parts. I'm quite pleased with the results. I know that there are various ways of connecting this processor to an amp but I went with the simplest way and I think the results speak for themselves. There is something about a guitar speaker and a mic that tends to remove some of the "nasties" that occur when going direct into a soundcard/desk.
