Just a followup - this morning in practice I tried to run my B3 into our powered mixer using the 1/4" unbalanced instrument input on my (bass) channel. Input was still just as hot as the XLR out. As I'd mentioned in a previous post, my other idea was using the board setting that attenuates the channel input. Attenuating my input sharply dropped the B3's input signal and allowed me to raise my B3 settings back up to 100. After that it was just a matter of tweaking the gain and volume settings on the board. I wound up getting a great tone and I'll happily use it tomorrow for our gig. This was the simplest solution for me. My sincere thanks for all of you who gave me welcomed advice. I will remain a daily reader of this important thread!
