...is the room your in. I did a gig the other night on a stage where my cab was a foot away from a 15' stretch of smooth drywall extending out to the dance floor. Could not buy a decent tone for a million bucks. It thought about it and suspect that in addition to a nasty middy early reflection, I was getting a lot of phase cancellation. As I turned up the lows it went straight from wimpy to boomy. I thought I might have tossed a 6l6 or a speaker at first, as it sounded like a browned out 6" speaker. Next time I'll move the cab to the edge of the stage or stick the bass player with that side.:AOK I got a great sound recently playing with a wall to my immediate right side. The key factor was that it was all varied surfaces and inconsistent shapes, including a fire place, a bookshelf and round columns and things. Just heavenly high end and fatness. Other stories of stage conditions giving you tonal heaven or hell?
