[QUOTE="Kevin Gleeson"] There are times where that works. I've often worked on gigs where we place the guitar amp facing the wall. Especially with Fender twins with an open back.[/QUOTE] Ho yuss. And sometimes a tilt backwards works wonders, but wall facing a Twin reverb is almost a necessity. [QUOTE] You can't draw that as a rule. It depends on the speakers, the amps, the room and a whole heap of factors. Fender twins face at the wall from about 2m work a treat. Point a Marshall at a wall and it will sound lke shit.[/QUOTE] Wot you said.
