You want input? I'll give you some input. The SM 58 is the same as the SM 57. The 58 has that nice metal ball with a little extra foam inside of it. It's the sort of adequate but an extra foam ball on top of the metal ball will work even better. Then you unscrew the metal ball to turn it into a SM 57 to put on your guitar amplifier. But you could also put the SM 58 even with the extra foam ball on your guitar amplifier and you won't lose anything by doing that. What you will lose his more than $100 on a computer audio interface that includes MIDI capabilities that are integrated within it for around $100. That's unrealistic. And even though Radio Shaft makes Realistic stuff, it ain't realistic stuff. And they don't have any of the realistic stuff you need or want. Don't even think about those crappy condenser microphones you've listed. They're crap. The 58 is your best investment. Watch any television with musical acts. 99% of the time, you'll see the singer on the 58. You'll only see them on something else when they requested something else or they were provided something else for free as an endorsement package. Nobody's going to offer you a microphone or computer audio interface for free. Certainly not a computer audio interface that includes microphone inputs along with a MIDI interface. So, what, you paid less than $100 for your guitar? If you did? Then you shouldn't waste $100 on a microphone to record it with. And then your computers soundcard microphone input would work perfectly fine with a seven dollar multimedia microphone. You might want to check with some of the jokers at Guitar Center since they don't know jack but are certainly willing to sell you anything you want that may or may not serve your needs. But hey, it's only rock 'n roll.
I only spent $150,000 and I still didn't get what I wanted. I wanted a gold record and they don't make those anymore.
