Sorry to say it man, but you NEED a preamp. Your mic will "work", but it will sound hella low, and quality won't be at it's peak. Here's why

Explaination of "What is Phantom power?":

The Shure sm58 is a Dynamic mic so it doesn't "need" a preamp, but it's comparable to me, freakin my $5 cpu mic hella good, if you don't use one. SO...

Get this:

It's one of the best preamps for the dollar value, PLUS, it's got a USB connection for us cpu guys who mix via cool edit/cubase/acid/etc, rather than a mixing board. On M-Audio's site it's $179.00, but I looked on ebay and you can buy it now for $149. Or you can even bid at a lower cost.
