I already have a Sure SM58, if I wanted to use that and another mic for recording vocals and guitar, which would this community suggest I buy?
Don't pick the USB version of the AT2020 please. The XLR version, being XLR, is just much more useful if you want to use an interface. Please consider changing your vote, I just added the non-USB version to the poll.
i don't get why anyone would want a USB mic ...
