I've recently been experimenting with turning the combo amps I use around 180 degrees and getting the sound mostly from the rear of the speaker. So far I'm loving the sound and find that it helps me play cause I'm loving the sound so much. I play in mostly small bars and clubs where there is usually no choice but to locate the amp directly behind. Our band plays blues , blues/rock, and some classic rock. In general, I hate the direct sound of speakers within close proximity, turning the amp around seems to create a more diffused sound and to my ears sounds much, much better. So far I've tried this with my Victoria Regal and my Fender Super Reverb with a strat that cuts well. Both sound great this way. The only minor problem is getting to the controls on the Super Reverb - not a problem with the Regal cause they're on top. I've tried the beam blockers and the "Mitchell Donut" but just turning the amp around has been a great discovery for me so far. We've also got good feedback from listeners. (our other guitarist has turned his amp around also) This might not work well in larger clubs/outdoors or with extremely loud bands. I was curious if anyone has tried this and can share there experiences? Much appreciated.
