Echorec,
I've been busy so I haven't had time to post...but anyways. Nice room.....any chance you need an assistant? I'd love to work in that place...one of the nicest live room's I've ever seen.
My suggestion would be to get the three so that they can all see and hear each other. I feel that Jazz is a lot of the vibe and feel as stated by someone earlier. It's important to get them into the mood and if you get a little bleed from the mic's then so what...the vibe is there and will transfer to tape.
Secondly I'd get them all set up so they're comfortable and let them play for a bit...then just listen. Then try to place mic's so that all you're doing is copying what you hear to tape. You don't want to mess with the sound...just record what they're playing and what you're hearing. I'd say set a u67 over the drum kit and adjust it untill you're getting a good sound...then if you really need to add a mic to the kick or/and snare. A u87 outside the kick won't hurt. For the piano I'd recommend a pair of u47's in spaced A/B and if need be stick another in the middle for good imaging. For the bass I'm not sure...maybe try a 122 just to see what happens. Maybe a u67..hard to say without a complete mic list and not hearing the bass in the room.
Then comes the room mic's...a highly important part of all this. Set up a couple of room mic's to finish polishing the track off....move them untill you get it right. That's a great room and I'm sure you'll get an amazing sounding track when it's all done.
I'd also stay away from compressors and reverbs and eq's untill you get the best sound you can..then if you have to use them. But clean and uncolored is the key here. Earthworks pre's, millenia pre's, things like that...if EQ is needed I'd use the 8900....stay away from pre's and things like Neve and API as I personally feel they will color the sound too much. JUST MY OPINION...no comments please all you die hard neve guys................
These are my suggestions..hope it helps a little..
