i would say it is a shure 520dx bullet, this does have some dirt on it but they do have a pretty dirty sound for vox as it is. then next to the 520dx is a shure sm58.
if you are after the particular sound of that mic then i would go for that mic because effects won't just make any mic sound good, they all have completely different characteristics in the way there are lumps and bumps in certain frequency bands as well as the polar patern ie: cardioid, super cardioid, hypercardioid, omni, figure 8 and so on and so forth, the cable, the preamps of the desk. etc
here is a very good place to learn about microphones, but in the end it is down to the listening and the engineer for how it sounds out front
