I recently had a ska-blend band in to do rhythm tracking, and will be overdubbing horns next week.

For the 'bone, I'm pretty much settled on using my Fathead.
The other horn is a sax... which has been a bit of a bugaboo for me.
I'll begin by echoing some thoughts I found while searching this subject.

1. The sax player (tenor) I've had the most experience Micing is an animal, and not in the flattering sense. Squawks, reed bites, strange achromatic runs, etc. When he fits, it's really nice. But his dynamics and sound are all over the map. We compare having him play to letting a rabid beast out of its cage: you free it, let it go wild, and (hopefully) put it back when done.

2. In the above, I've tried a Bluebird, a clip-on (UGH!), a 414, and a Fathead - with varied success. This includes double-mic techniques. Again, varied success.

3. When Micing my clarinet, I've had good success w/ a 421 near the bell and a Bluebird near the left-hand fingers. So any thoughts on a double-mic? Note: did not have the Fathead @ this point.

My initial thought: Go w/ the FH a few feet in front and somewhat above the sax. I love it (no it's not a Beyer or Royer) on many sources (gui amp, female vox, strings). It's quickly becoming one of my favorite mics. I'm figuring it should perform well in this case, too.

However, I do record in a large church sanctuary. 30'x40'x15-30', vaulted ceilings, of course. I have other spaces/rooms available, although all but the "control room" are subject to lively, larger spaces - to one degree or another. If you have the itch, I've got a model using Sketchup available for d/l:

Point being, I am a little concerned about the space included using either a ribbon or an LDC. I like my room(s), but sometimes get too much of it(them).

Oh yeah, and the sax player for this session will be playing mostly alto, although likely some tenor, too. He's much more disciplined and skilled, to boot. So I'll be dealing with a much tamer animal in this case.

Any thoughts/suggestions would be greatly appreciated!
