| S | A shallow “bowl shape. These cups are the shallowest depths available. For unusual upper register demands or the Alto trombone, these models perform well. | | M | These are medium depth with a modified “V” contour. The M cup is preferred by players doing lead work in big bands. | | D | These deep cups produce a very full sound and are some of the most popular models. | | ST | Symphony Tenor models. The large cup volume produces the ultimate in sound to fill the largest auditorium. These cups should be used with the ST model backbores. | | B | All of the B cups are very deep models that are intended for use with Bass trombones. Combined with the B series of backbores, these models will excel in the low register. |

|---|
| T | Bore .250”. The T series is standard for Tenor trombone. They are numbered 1 to 6, with 1 being the smallest and 6 the largest. | | T * | Bore .250”. The T * (Star) series is the same as the T series except there is no cylindrical section. The T * models are more free blowing than the standard models. | | ST | Bore .266”. There are 3 models for the ST backbores. They are numbered from 1 to 3, with 1 being the smallest. These models are designed for the large tenor; it is not just a tenor backbore with a large shank. | | B | Bore .281”. The three B backbores fully complement the Bass cups with a full sound that is rich in harmonic overtones. They are numbered from 1 to 3, with 1 being the smallest and 3 the largest. |
