The Funkin Groovin rim is wide and semi-flat, but is nicely rounded on the inside. There is a high alpha angle for a gentle slope into the cup. The width of the rim helps offset lip swelling. There is no undercut for chop room, so it will feel true to the .615″ inside diameter. The cup is a shallow V (similar depth to Bach E). The entrance to the throat is very receptive to good air flow for a nice big sound. Slotting is excellent with the Funkin Groovin. This model was inspired by a classic mouthpiece familiar to many. The Funkin Groovin has been updated with the Legends enhanced throat (#27), enhanced throat cylinder length, and Legends S backbore. These design elements maximize endurance, range and sound for the player. The Funkin Groovin is well suited for extreme upper register work, extended upper register playing, and for really groovin’ high above the staff!
