Generation X mouthpiece series. Ultra light models with very wide support. They range from a 14XS diameter (a little smaller than the traditional 12) to a 28XS diameter which is almost a trumpet mouthpiece chamber. Ideal for high registers, heavy-duty work where small chambers and very wide supports help a lot to support the embouchure. Ideal for field work, troupe, military marches and first popular music trombones.
