The rim is only half of the equation! Dial in the sound and support you are looking for with one of our three cup depths:

The large bore tenor trombone models include:

• 3     Our largest cup in our large bore line.  Very open and free blowing with dark tone concept.
• 4     Very open and free-blowing. Great for orchestral 2nd part playing.
• 5     This offers excellent core production and balance across all registers.
• 5.5  Similar to the 5, the 5.5 features slightly smaller rim diameter for those looking for the added support.
• 6     Provides a focused sound and a dense core. Excellent for players that prefer smaller equipment.

Each cup requires the respective diameter rim.

Each of these come in three different cup configurations:

• D  Our deepest cup in our stock options, providing a very free-blowing experience.  The extra depth allows for a warmer and richer tone color in the low register, without sacrificing the upper register.
• M  Our medium cup is the most popular model.  It is a middle of the road cup designed to appeal to a broad range of performance genres.
• S  Our shallow cup provides more support in the middle and upper registers, adding some extra brilliance and efficiency.
