Yamaha Custom Series Large Shank SL-48LGP Rim Diameter: 25.25mm Throat Diameter: 6.62 List Price: ¥18,150 Purchased about 6 years ago and stored for a long time with little use. Although it has been stored carefully, I have decided to sell it to organize my belongings. There is no sign of use, but there is some discoloration of the plating due to long-term storage. Product Description: It has a very well-balanced rim and cup with a narrow back bore. It has the ability to meet the advanced demands of professional musicians and is highly complete.
