i just got my first recording and modeling system for the computer and i dont like the amp modeling. i was wondering if i can mic my amp and then put it through the software to record. what is a good cheap mic to buy. could i also use the same mic to later record vocals. my interface has a input for a mic. i have seen mics with a 1/4inch jack as well as mics with a XLR jack is there a huge diffrence between the two mic jacks. my mic budget is about $50.
