Ok, so as you may know, I run live sound for bands. I only have SM58's, and a Beta 58a. I like the Shure's alot for the fact that they can take a beating, and since I let many, random people use the mics, this is important. I find that often times, on a male, the SM58 is easily lost in the mix. I find that the Beta 58a is a little more clear and present than the SM58, but you have to sing more directly into it, which is hard for some singers who move around alot. Although, the Beta 58a on a female (in my experience) wasnt great. Now, I ran sound for a band recently that used a wireless E865, and man was it phenomenal, but way out my "loaner" price range of up to $140. Versatility is of course important, but what makes something stand out for an application? I know mic technique, eq, music style and other factors are big things, but I'm just looking for discussion. What mics in this price range do you use, and what exactly do you use them for? Maybe I'll be buying something in the future. Pro's, con's, selling factors....state your claim! Also, Ive got an SM58 or two that are older, slightly beat up looking...is it possible that these could sound different than a newer one? Aside from physically being hard on it, what about "over singing" (for lack of a better term) and wearing out the....."cartridge?" ???
