Please Note: This cup requires a screw rim to be a complete mouthpiece.
Similar to the GS, an excellent all-round mouthpiece developed for Gene Standley, the GSL cup is slightly S shaped and offers substantial cup volume for a full sound. The cup has medium depth and in this version, the throat is modified to allow great facility in the lower range of the horn. An excellent mouthpiece for 2nd & 4th horn.
Giardinelli threads are standard.
