When I record my amp with my sm57 which is plugged into the 1st mic pre in my firebox, I have to turn the amp really high and have the gain on the firebox up high to even get a signal. I thought I could mic my amp and play reasonably loud and it would get a reading, like how loud i'd have it if I was just practicing myself.. But I don't. I really have to crank my amp if I want to record it. What I want to know is, is this normal? If not, what could be the possible problems? Oh and one more thing. I put the mic right against the speaker cone so that it's touching it a little. So it's not like I have the mic set up 5 feet away from the amp or anything.
