What more can you save, SM58 and 57, the industry standard.
Just don't waste money buying cheaper miss, if you have the cash get something better but never go lower. These will give you years of quality service.
They sound great on snare, toms, bodhrans, cajons, electric guitar cabinets. Even sax and most other instruments, give it a try. Some vocalists even seem to sound better with a 57 rather than a 58.
Just make sure you buy from a reputable dealer, never on Ebay, there are just too many fakes on the market. First thing to do when you get yours is to weigh it, if it is less that 270 gms its a fake.
