【LASKEY / Joseph Alessi 60SOLO】 This mouthpiece was designed under the supervision of Joseph Alessi, principal trombonist of the New York Philharmonic and a world-renowned trombonist. It features an open feel due to its wider throat diameter, allowing for a dense and powerful sound. This is the solo type of the two types (solo and symphony), but it can also be used effectively in ensemble playing. The size is 60, with a slightly large inner rim diameter of 26.0mm. There are some minor scratches, but it is in overall good condition. The case in the photo is included.
