Hi Donny,
I used an SM 58 for 35 years until recently. I do Wednesday nights at the top of the Hyatt Regency here in Baltimore. One of the other guys that also plays the room was in one night from another gig and he had a Neumann KMS 105 with him. During the break he asked me if I wanted to try it out and I did. Wow, what a difference. I have a project studio and I've always been a Neumann fan for studio use, but I'd never considered using one live. Well, 2 days after that night I had one and I'm very happy with it. It gives you the transients that you just don't get with the 58. I'm not familiar with the Sennheiser that you'r looking at, but they are a great studio mic as well. We've all upgraded our other equipment over the years, I guess it's time we did the same with our mics. Good luck with your choice. And also, thanks for the info on the Thursday night gig.
Joe
