Since this forum has become something of an avatar archive, I figure Ill post my experience with them. I got my B212 neo from the factory friday, and it sounded great as I was running through some rock/fusion/jazz stuff at a fairly low volume with the tweeter low. Then I remembered that I had to play 2 solo peices at a gig that night, so I turned some knobs to the 'Victor Wooten' setting and began. This involved turning the tweeter and volume up, but not anywhere near distortion levels. It sounded really good until I hit a 'G', and the the tweeter emitted a shrill, metallic buzz. It was fairly loud, and varied predictably with the volume of my playing, although it seemed to have a threshhold under which it wouldnt do it. I played around, and it did it for every 'G' and no other note. Tried another bass, same thing. Tested it again at the gig incase it was a room resonance issue, same thing. If I left every other knob the same and turned the tweeter off, it went away. I've emailed dave, no response probably becuase its the weekend.
