Diameter: 26.90 mm Cup Diameter: 16.75 mm Rim Width: 5.07 mm Bore Size: 3.70 mm Back Bore: Barrel Heavytop models use a completely different principle in not feeding back to the player the vibration of the instruments, transmitting all the energy through the bell. This gives a much more powerful sound when needed, more security in the high register and more control and focus in all registers.
With the large-bore C trumpet in mind, this model is more brilliant than the 1 and 1X, and manages effortlessly to dominate the modern symphonic brass section.
