The Screamer has a soft round rim which is very comfortable. The width of the rim helps offset lip swelling, and there is some undercut for chop room. The inside rim diameter is small (.590″), and is paired with a very shallow V-bowl cup. The entrance to the throat is rounded and very receptive to good air flow for a nice big sound. Slotting is excellent with the Screamer. It has the Legends enhanced throat (#27), enhanced throat cylinder length, and Legends S backbore. The design elements of this piece focus on accentuating upper register playing while improving endurance and maintaining intonation. As the name indicates, this piece is perfect for screaming lead!
