I had a gig where i needed to mic a choir, so after doing some research I bought this mics. What to say, I wasn't disappointed. They are not the best mics for the job (let's be honest - they are not expensive either), but they do the work excellent. The sound was very good and warm. I was very satisfied.
After that, I used it on guitar cabinets, recordings,...
Once i had an opening of a festival and i used this mics for speach (people don't know how to stand in front of a mic, so the sm58 wasn't good for the job) and it was great help!
The sound that you get from the them is excellent (for the price you pay), you won't be disappointed even if you use them for some recordings of acoustic guitar and voice.
I have 4 of them, and they are now a must have in every live gig i do.
I would definitely recommend this mics, they are great all-around mics!
