I switched from an Omni Directional mic about 8 years ago to the unidirectional Crown CM-311A and that ended all feedback problems with any sound system I used. I have three Crown CM-311As, one stays in the office, and two go with me - just in case. In all these years, and thousands of jobs, I've never had a failure using the Crowns.
As for the distortion, I guess it's possible with any sound system that is overdriven. I just don't crank the volume up to those levels, therefore, I've never experienced distortion with the Bose systems.
Fran, the next time I'm up your way I would love to meet up with you, Dave and Donny, and possibly go hear Gary Murway perform. Maybe one weekend in September. On October 1, if my health holds together, I'll be sailing south for the Florida Keys and Bahamas.
Cheers,
Gary
