I haven't had much luck using a dynamic mic...
I got a Behringer C-1 low grade dog food condenser mic for $19 on sale ($45 normally). And it is the best guitar mic I have ever used 
Most of my profiles have C1 after them.

Since you can press REFERENCE AMP, you should be able to dial in the amp sound with music before profiling? But that would still be song dependent. So maybe not much help overall.
