The SH Lead has a semi-round rim which is wide and soft for maximum comfort. It has some alpha angle for a more gentle slope into the cup. The cup is medium shallow, similar to a Bach D. The entrance to the throat is rounded to allow good air flow for a nice big sound. Clients that have played the SH Lead have described it as feeling similar to a Yamaha Shew Lead. It is not a copy of this piece, but has a similar rim and cup. The SH Lead has the Legends enhanced #27 throat, enhanced throat cylinder length, and Legends S backbore. These design elements maximize endurance and range and improve slotting for the player. This mouthpiece is well suited for screaming lead, but is versatile enough to play legit music, too.
