Endorsed and played by the legendary Dan “PeePaw” Burnham! The rim is semi-flat, but comfortably rounded on the inside and outside edges. It has an inside diameter of .626″. The cup is a shallow to extra shallow v-bowl (similar in depth to Bach E/F). The throat is slightly tight, #29, and the backbore is the Legends Manhattan (very focused). Put these features together, and you have the support and resistance needed for extended upper-register playing, without sacrificing comfort and control. This mouthpiece embraces your embouchure with steadfast comfort and support just like a hug from your PeePaw!
