I don't know if this is the right forum or not, but maybe you guys know. The other night I brought a new 1x15 to a gig with a band where I set up next to the keyboard guy, who brings a Leslie. He brought a different keyboard to drive it, a Hammond slab of some kind. In rehearsal, he plays a different keyboard through a small Peavey amp.
Here's the problem: for the first three or four songs, I would get this queasy feeling I was grossly out of tune, especially when I'd hit a G on the E string. I finally signaled the drummer to hold up, and checked my tuning. I was a few ticks sharp on all strings on the Snark, but nothing unusual and it usually comes in after playing a while anyway.
On the next song I glance over and the keyb guy has his left hand way over at the bottom of the keyboard. So I lean over and tell him to roll off his lows. I figured he was just stepping on my low notes and I wasn't hearing my own root notes, but rather his scale tones nearby in frequency. The rest of the gig went fine. He later protested that he hadn't been playing much down there, but I'm not so sure. Anyway, it now occurs to me that maybe the rotating woofer thing had something to do with it, maybe a Doppler shift when he was hitting the same note as me.
Have any of you experienced anything like this when the bass amp was next to a Leslie?
