You can plug the mic into a regular amplifier. Problem is, if you guitar is distored so will ur voice. So it's better to use a different amp then the one u use for your guitar.
The mic needs a special cord. At one end is the regular jack that plugs into the amplifier and at the other end is a circular jack that plugs into a mic (and if i remember correctly mic jacks are fairly expensive)
Get a good, name brand mic. They are like guitars, if you get an Epiphone Les Paul Special II it's not gonna sound like a Gibson Les Paul original. You will hear, and feel the difference.
