Just got in after using the 855 on the job. It's a really good mic. Very little e.q. necessary, very feedback-resistant, very smooth throughout the sound spectrum.
It compares favorably with the SM87, which is a condenser mic. Pretty much blows away the SM58. I haven't used an EV in a long time, but it sort of reminds me of the older EV condenser mics, except better.
I use the really cheap Behringer mics for guests, and they are remarkable for the money. Very close to SM58, and something like 3 for $50.00!
