This mouthpiece is built for screaming lead! The rim is extremely comfortable with some nice undercut for chop room. The cup is very shallow (similar to Bach F), with a drop V shape similar to the famous “SL” cup. The entrance to the throat is rounded, which allows plenty of air flow for a big sound despite the small inside diameter. Slotting is excellent with the L-BL6. This Legends model was inspired by a famous mouthpiece familiar to many. Ours is not a copy of this piece, but has a similar rim and cup. The Legends L-BL6 has the Legends enhanced throat (#27), enhanced throat cylinder length and Legends S backbore. These design elements maximize endurance, range and sound for the player.
