I play an Edwards B454, with a B-STD slide and a Rose SR Tuning Slide.
I have two bells. A gold brass brass 10 inch 1574CF for heavy symphonic playing
and a rose brass 9.5 inch 1117CF for classical works, big band and some solo playing.
I use a number 3 leadpipe for most symphonic works,
but for some classical or chamber works and solo pieces I use a number 1 leadpipe.
My mouthpiece of choice in a Vincent Bach 1.5G for most things and occasionally a Bach 1.25.
