I have a Vox VT40+ & VT80+ that both come with plenty of preset sounds and still trying to work my way through the 99 or more combinations. The little one is plenty loud enough through a 10" speaker and the bigger one can become a bit too loud through the 12" speaker.
The 1,500 watts for the Line 6 is a bit of an overkill too, even if they are borrowing ideas off PA's as who really needs that much headroom? Probably only stated to help justify an exorbitant price tag.
