This classic, but modern mouthpiece is perfectly machined with a medium-weight blank. This large bore model is available in 5 sizes and silver or gold plating. This is the ultimate trombone mouthpiece with perfectly balanced models.M Cup | Medium A medium depth cup that spans both small bore and large bore models, the M is closer in feel to the 6-1/2AL, making it a standard for those who prefer a great feeling and playing all-around mouthpiece. MD Cup | Medium-Deep Similar in feel to a 5G, the Laskey MD represents a medium-deep cup that is a significant upgrade from the standard G cups of the past. Emerging from a strong low range through to the high register, the MD provides an optimal balance and resistance for a wide range of genres and styles. D Cup | Deep Deep, but not as deep as the 51D, the Laskey D Cup is unlike any other you've experienced on a symphony (large) shank mouthpiece. This relatively deep cup gives players a rich, textured tone that feels at home in the principal or second chair. Sometimes, more is more. Comparison Chart Measurements Metric Imperial
