I was most recently a member of the Stan Bann Big Band. Currently I'm not playing in a band -- but I occasionally sub with the ACME Jazz Company, which is composed of many former SBBB alums.
For those (very few) that might care, I started on a Holton "Collegiate" made in 1947 according to the serial number (175XXX). It has a "Collegiate" mpc. No idea what size it corresponds to. In the ninth grade, I got a Schilke B3, (large bore, medium bell) and I've been using that horn ever since. I also have an early 60's Severinsen Eterna (pre-amado-water-keys) that I play (actually, most of the time). Less work than the large bore.
I used to play on a Marcinkiewicz E13: "Chuck Findley" mpc. Now, I prefer my GR 66MS. It seems to give me enough flexibility in the sound so I can use it in all of the kinds of situations in which I play, without having to switch, sound too bright, get my sound buried, or my tail kicked by a too-big mpc.
I've played (at) the piano since I was 5 or so. I'd like to learn jazz piano. I recently was directed to a great book by Mark Levine called "The Jazz Piano Book". In it is a lifetime of work...
There are so many good places to visit that Ralph's already points to, that it's just easier to let him maintain the links. I seem go back to these:
