I have a Korg D12, and can get some nice clean almost acoustic sounds when going direct, but would liek to be able to get the sound I hear when I play through my amp. I use a single 15" sealed cab for my guitar. I really like the sound I hear when seated not far from my amp. What type of mic would be best for placing where my ears would normally be? I currently only have an SM-57. ANy other suggestion on how to get that same sound recorded? Thanks.
