Independent shopping perspective
Built for large tubas, the 1L Heritage Series mouthpiece pairs a 32.5mm cup with an 8.43mm throat. Its thin cup wall near the rim and added mass at the base are intended to combine quick response with a rich sound and a more accessible upper register. The 1L is the high-output option in the range, offering enormous volume and range for players with the strong embouchure it requires. Gold plating on the rim and cup contrasts with the silver-plated body.
