I bought a Shure SM58 mic and I have a Soundblaster Live Plat 5.1 I need a mic pre amp that's fairly cheap. Any suggestions on a name a brand. I want the pe amp to be under $100 canadian. My local Mother's Music Store suggested a pre amp for $60 called the Midi Man or something but they were out of stock. They are out of stock of all pre amps till next week so when I go in next week I want to know what I should be looking for.
