The Legends Thunder has a semi-flat, very soft rim with some undercut for chop room. The cup is based on the famous “SL” cup, and is medium shallow. The entrance to the throat is rounded, which allows plenty of air to pass through for a nice big sound. Slotting is excellent with the Thunder. The design elements of this model combine to enhance endurance, range and sound for the player. This piece is great for lead, legit, or any style of playing!
