Shure - PG58-QTR

Yes, the SM58 is considered the "Standard" for vocal mics, especially for Live use. Thing is, it's been around for a very long time. Most budget mics makers try to imitate it as best they can. Even Shure tried to duplicate it's performance in more economical packaging. The PG58 is a good mic, but not quite the same feel of a SM. I think it may be just a matter of the weight of the casing that makes the difference, one heavy metal, the other lighter weight, more plastic. I suppose there may be some different resonance factors between the two, as I believe they use the same internal cartridge. The difference being the SM seems to be more resistant to noise than the PG. For the longest time, I used an SM57. I have a bit lower, softer voice and could put a touch more gain on it and it caught my voice well. If I backed off it and sang louder, it still worked well. But, after 40 odd years, it gave up. I replaced it with a Peavey PVi2, and so far I have been pleased with it. I don't expect it would last as long, but I also don't gig as much, so I think the trade off is okay. The PVi2 is Peavey's version of a SM58. If you are on a budget, I recommend them. Comparing dollars to donuts: (approximately) Shure SM58 - $100 Shure PG58 - $35 Peavey PVi2 - $50

The Yeti is a fine mic. But if your issue is background noise you should look at a dynamic mic vs condenser - SM58 is a good choice. If only speech a PG58 would work as well. Also, beyond the mic, what are the acoustics of the room? Any sound baffles to limit noise? The mic needs to match the room and the use. And as someone already said, this is a problem that can be solved for well under $1,000
