Hello, I just purchased a MBOX3 Mini (was borrowing an MBOX2 Mini.) I mic my amp with a sm57 next to the grill cloth, and run to xlr input in back of the MBox. I have to have my amp up pretty looud and the gain input turned 3/4 or more , jsut below peaking to get proper input(yes, the -20 pad is off) . This does not seem right should not have to tuyrn up so loud to get good input, driving my wife crazy... Anyone else have the same issue with the MBox3 mini? Seemed ythe MBox 2 was more sensitive , better input level.
