The L-BL4 has a soft, semi-flat rim that is wide enough to help offset lip swelling. It has nice undercut for chop room. The cup is shallow, and shaped like the famous “SL” cup. The entrance to the throat is rounded, which allows good air flow for a big sound. Slotting is excellent with the L-BL4. This model has been described as feeling similar to some of the smaller Monette pieces. The rim and cup are similar, but It is not a copy. The L-BL4 has the Legends enhanced (#27) throat, enhanced throat cylinder length and Legends S backbore – design elements which maximize endurance, range and sound for the player. Customers that have played this model have used it for extreme upper register work and extended upper register playing. It’s perfect for solo and screaming lead!
