We did a lot of research before buying vocal microphones for our band,
After checking several brands and models, we found this SM-57 clones in a LA music shop.
After reading some experience from other users we decided to buy a pair, and let me tell you, one of the best purchase ever.
The build quality is great, solid, it look like it will last forever.
You can tell it the first time you grab it.
About the sound quality , i have to say, its very very good,
It's clean, good presence, suits very good every singer who has tried it
Its has a good bass response, but not that strong below 90 Hz, so that makes it clean and avoid rumble or any feedback on stage.
The highs are clean and not harsh at all, i think is great for male and female singers
On stage it behaves really good, with great feedback rejection, and sounding strong just like a real 58 but for a fraction of the price.
It might has a little more hot output that the original 58
For 29 US you won't find any other better mic on the market,
I think this is a must have for every touring band that need a workhorse mic for rough situations.
If you are thinking it, i would say go for it.
