It's not an SM57, but it is very close in looks and sound quality. On amazon you can get these for about £11 and although they are fairly cheap, they sound professional and can get the best out a snare, guitar, bass or toms. I personally use it for Snare, High Tom, Floor Tom, High Hat, Guitar and Bass Guitar. I always get the best quality out of them using these microphones. I was surprised how perfect they sounded for mics that costed £11.
If you don't want to spend loads of money then these are the microphones to get, you can get the best sound out of your instrument with these and they give you a clear, professional tone.
