Yes, it's true...at tonight's gig, i laid my svt 810 on its side. i can explain...i totally forgot that the stage was so small that only our drummer and keyboard player could fit, and i, the guitarist, and sax went on the floor in front. but the stage was only 2 feet high, so i would have blocked off the guys on top, so i had no choice but to lay it down. i'll never do it again, though...our drummer fronts the band and gets up off the drums in between some songs. where does he stand? on my cab. grrrrrrrr!!! ok, so it's beat to hell anyway, but still...he's not a small guy. so how did it sound? fine in the house, i guess. i kept it down and mic'ed it to keep it from sounding like crap. but i wasn't happy with my onstage sound at all. didn't help that my mic stand was in a zone where all the low notes phased out on me. and the second i kicked on any overdrive pedals, the sound was just gone. so now, for the first time ever, i know what it's like to play in front of a horizontal 810, and just like everyone who knows about speaker science says, it blows. don't do it.
