hmm i would take the L + R out of the tascam using phonocables > mini jack and record them onto computer using ur line in and some software, then burn em off, hey presto! needed equipment : computer, cables, software For recording i would use an SM57 also cuz they just sound gr8 for what they are and price wise. Get ur hands on an NT2 for vocals i love em! SM58's are good for live vocals because it sounds great and its a proven classic mic and its got a really flat polar response but give a Sennheiser 935 a bash you would be surprised how good they are and their not a whole lot more than the SM58 in price!
