Ok, here's an interesting little thing that's been bugging me. I went to ITG for a day, and played literally, everything (my lips were throbbing). I was very excited at the thought of playing the legendary Schilkes. I'd heard that they were excellent horns and some said that they were also very open. I had my Bach 3C (standard, not megatone) for playing as that's my usual mouthpiece. Then I picked up a bunch. I tried the B6, and that one felt stuffier than an attic. I tried and S22 and an S32- slightly better, but still incredibly stuffy. I then picked up an X4. THAT was even stuffy. The valves and everything were great, beautiful horns, but the blow was stuffy, and the tone sounded stuffy as well. Has this happened to anyone else? It's just really kinda weird that I felt that way on pretty much the whole line.
