Bach Strad. http://edition.cnn.com/2001/CAREER/trends/02/22/nyphil.trumpet/ Edit: Sorry, I thought it was in there. I've read it somewhere that he plays a Strad, however. (amongst other horns including an Eterna cornet).
Yes he plays Bach. Well a Bach Bb and C anyway. I believe he uses a Schilke P5-4 Picc and a Getzen Eterna Cornet. All of this info is available on the liner notes of his orchestral excerpt CD. Ther liner notes of that CD also include which horn he is using for each piece as well as the mouthpieces and mutes. Interesting info I guess if your a gearhead.
Much of this information, and more, is included in an article about Philip Smith in a UK magazine called The Brass Herald. It's published 4 times a year and more information can be found on The Brass Herald website; www.thebrassherald.com
