I spent a lot of time today on my cello quest. In the end, I picked the SM57, and the Sennheiser e906 (mainly because I'd been using 3 of them for a Queen Tribute - and they did quite well on AC30 amps. I went with the AKG 414 and the U87.
I am recording cello and piano in a small-medium size room that is too bright and live acoustically - I can't really treat it except to put a blanket under the piano.
What mic setup would you all recommend? I always used X-Y stereo on 2 small diaphragm cardoid mics and a large diaphram cardoid as spot mic up close (6 inches).
