you're welcome. anyway, what is that LMD sax mic? Is it a clip on? small diaphragm condenser or dynamic? I'm unfamiliar with it.
getting back to mic cabinets, obviously none of us here use thirty or forty mics at any one time. But there are other reasons for having that many.
In my case, many of my mics that are used in the studio I wouldn't use on live sound gigs, and visa versa... and I need both types. But even just considering studio use, the best argument for a large mic cabinet is so you have choices. No two singers, sax players, etc. sound alike, as you well know. And the perfect mic for one might be perfectly awful for another. A lot depends on the type of music being recorded as well. Since you are a sax player, think of the difference between recording King Curtis vs. Ben Webster... Or Johnny Hodges vs. Dave Sanbourn... Surely it's likely that the best mic for one wouldn't necessarily be the best for the other. (Yeah, I know, I picked a lot of dead guys, but you get the point...)
Have you ever seen a session where the drummer brings three or four snare drums, and changes between songs? Or multiple cymbal options? It's really quite common, and drummers in my studio do it all the time. The reason is because what is right for one song may not be right for another.
It's the same thing with microphones. No one says you can't make a good CD using the same mics on every song, but it's just one of the ways that the big studios, with large mic inventories, get a better sound than the little guys.
