So I have one of these newfangled Kemper profiling amps. You have to mic your amp to get it into the Kemper. I'm finding that GIGO applies here - garbage in, garbage out - so I'd like to improve my amp miking chops. I have an SM57 and an E609 Silver. Last night went to GC and told the guy what I wanted to do - he recommended trying an RTA-M mic from dbx. It's a reference mic and has really flat response. I tried it last night and it was ok. I'm wondering about a ribbon - maybe something cheaper like a fathead, I don't want to spend the $ for a 121 Royer. I'm thinking Fathead + Sm57 would be a nice blend. Comments/ideas/links to anything/brickbats? Thanks in advance.
