hey guys, i came across the email from the admin about the Dillon Music contest and i realized that i'm actually rather clueless about some stuff here. "1st Prize: A standard model Bb or C Bach Stradivarius trumpet in lacquered brass or silver plated finish customized by the Bach Custom Shop at Dillon Music. " i read in forums that there are different lead pipe sizes, bell sizes, plating, mouthpiece sizes and such for a trumpet, what differences do they make? how important are these stuff? what about the different brands? cheers!
