Yesterday I was in our rehearsal room with my drummer and I tried mic'ing my :evil: Line6 :evil: Spider with a SM58 (without the metallic protection) since there weren't 57's at the moment and... :shock: wow :shock: , I don't know if I found a magic mic position or the perfect equalization on the mixing console (old sh!tty mixer by the way), but the tone was amazing and probably the best I've ever achieved (haven't a great experience however, just some experiments with home recording and a dozen gigs with a mic'ed amp), full and crisp, maybe a bit bassy but nothing annoying or unsolvable. I was not recording, just playing through some amplified cabinets to find a good tone for the next live dates. So, have you guys ever tried a SM58 for mic'ing a guitar amp and what do you think about it?
