The Legends Jazz Solo has a semi-flat, very soft rim with some undercut. The cup is medium to medium shallow depth, similar to Bach C/D. The throat is a #27, and the backbore is the Legends S. Slotting and intonation are excellent throughout the range with this model. We worked with a well-known Nashville performer and sessions musician to develop the Jazz Solo. His goal was a really nice smoky jazz sound, on a piece comfortable enough to play all night. Try it in the heavyweight blank to add more core and further darken your sound.
