Here's a webpage listing the equipment many pros are purported to use: http://www.trumpetplayersdirectory.com/trumpetplayersequipment.html Today, I own 2 Bb's: A Schilke and a Bach. Both great horns. Both different. The Schilke's partials/slotting are zippy fast where the Bach's are firmer. The Bach's timbre has a denser body while the Schilke's timbre is . . . is . . . more lively (there, I'll use lively. The Schilke's blow is more open than the Bach. About the high registers, neither horn provides a magic bullet to play higher than the guy next to you.
