The Legends BC Master trumpet mouthpiece is based on Bill Chase’s custom 6A4Ac, manufactured by Schilke in 1971. A modified version of the 6A4Ac became Schilke’s famous 6A4A. This mouthpiece is very popular and there are several product reviews below. Also available is the BC Master Flugel mouthpiece. It has an identical rim, which makes switching between the two very easy.
