Description
The 64S has the same ID as the 64ES, 64LV and S10A4A. The cup is deeper than the above mouthpieces, and similar to a Schilke 14A4A cup depth.
This is a great choice for playing lead and is popular as a piccolo trumpet mouthpiece when a balance between a brilliant upper register and full low end is desired.
The sound is darker than the 64ES or LV, with a better low end, but not quite as much support in the upper register.
