Feature:
Not many... But this microphone is the major feature and since I'm so happy with it, I give it a 10!

Quality:
It's a Shure. Not only does this thing weigh a ton and feel like a tank, but it's also survived the famed Shure Drop Test. You can't go wrong with this product in quality. I really expect it to outlive me.

Value:
I would easily, gladly pay twice what I did. I think that Shure's list price is actually quite a fair price. You're buying a product that has been time-tested - one that you know won't let you down. This mic was well worth my money and would be well worth yours, too!

Desirability:
I bought it, my second guitarist is already saving up, and my drummer plans on using it to mic his snare. So, yeah. It has it's appeal!

Sound:
This is where the Shure Beta 57A shines. It sounds so clear. It is a pretty big step up from the older SM57 and since it is a supercardioid design, it has much more rejection to ambience and outside noise. I use this mic primarily to mic my amplifier and it is amazing. I get completely different sounds depending on where I place the mic. It's really a lot of fun. Very clear, real sound.

Support:
I have dealt with Shure. I was asking quite a few questions before I decided to get the mics that I did, because I didn't want to make an uninformed decision. And Shure support was right there to help me every time. I'm very satisfied not only with the product, but also with the manufacturer. Shure rocks!

Overall:
This CAN NOT be beat as an instrument mic. There are much better vocal mics (like the Shure Beta 87A - which I also own), but as an instrument mic, this is simply the best. I am so pleased with this microphone! If anything were ever to happen to it, I would definitely buy another. I love this mic, everyone I know who's heard it loves it, and I know that you would too. This microphone WILL NOT disappoint.

Feature:
no switches makes this mike even more solid and rubust, less problems to deal with. It is a very simple yet powerful microphone.

Quality:
Built like a tank, and feels very tight and compact.

Value:
I got my Beta 57A for the price of a SM, so for me its pure value for money. It compared very well with my Nuemann TLM 103 and Rode K2, although not as toppy sounding.

Desirability:
It looks like a Industry Standard mic, it has a very professional neutral look with the nice blue rubber ring. Its looks better than the Beta 58 ball, and IMO it sounds better too.

Sound:
Beautiful Natural Soundind dynamic microphone. It captures pretty much anything with the upmost detail and clarity focus. It sounds stunning on female vocals, and shows 'No' sibilance unlike so many condensors. The Beta 57A is much better sounding than the standard SM57 and SM58, which can get fairly harsh sounding with a nasal quality. The Beta version is smooth, warm and has a better top end. The midrange is very flat and works very well on most singers. I record in the studio with the Beta 57A all the time, and use it over my Rode or Neumann depending on the singers voice.

Ease of Use:
Plug n Play, and hit record.

Support:
Never used it.

Overall:
I plan to use this mic on everything, including lead vocals. it works so well.

Feature:
You Could almost Hammer Nails with the Beta 57

Quality:
I have three they are fantasic. My Nruman and AKG 414 TL is not going on gigs. But this Beta 57can go anywhere.

Value:
Can't beat it.

Desirability:
very cool looking better then the 58 ball.

Sound:
There is a nice Windscreen. Comes in Handy.

Support:
Never needed Shure support in over 30 years of owning their mics.

Overall:
It will out live me. Is that good or what?

Shure has always been the stage mic to have for
its quality and durability. The Beta series takes
this quite a bit higher... Same component strength,
coupled with a more responsive midrange, which
is good for my somewhat thin voice. The guy at the
board loves it for it's even response and "workability".
If you need a stage mic, get two... One for your
vocals and another for the amp.
