SM58 LC : Good, but not the best

Well, firstly, it does what it is known to excel in. Not picking up noises that are far from it. I brought it solely for that as I live in a crazy house, basically a fish market. However, this mic does not produce recordings as accurately or with details of the vocal sound even at a close distance to the vocalist. It is hard when you want to do loud vocals and want it to record the precise details of the loud vocals as well. I think if you want the details of the vocal, you need to increase the sensitivity/gain right? Then if you increase it, this mic will give all the distortion and muffled sound you can find when recording the loud vocals. Then if you stand further, the vocal details are gone. It is a bummer.
