Marking	Description	Stem
XS	Very shallow cup and tight throat to facilitate the upper register. The 14XS is for alto players desiring a good solo sound.	Small Only
S	Less shallow than the XS, but still a brighter playing cup. This cup is mated with a tight throat for a lead-type sound. Can also effectively be used on alto	Small Only
M	Medium-depth cup with a V shape. This is an extremely efficient cup with the capability of duel use between section work or possibly lead on small bore, or solo work on large bore.  .257 throat/T2 backbore (small bore), .265 throat /T5 backbore (large)	Small or Large
ML	This is the standard cup within the Hammond Design trombone line. It has aspects of both conical and bowl shapes to help become the all-around choice of most players looking for a focused, yet colorful sound.  .265/T3 small bore, .281/T4 large bore.	Small or Large
L	This cup is deeper than the ML, but with the same shape carried further down in the mouthpiece. For those players needing more low end in their sound or for the principal player needing more "space".  .281/T4	Large Only
XL	Extremely deep cup that is a great euphonium set-up. The 12XL is the 51D comparison players have requested.  .281/T4	Large Only

​TROMBONE BACKBORE INFORMATION:

Marking	Description
#T1	A tighter backbore for a brighter sound and more resistant feel.
#T2	Like the T1, only with more openness in the midsection. This creates less resistance, therefore more depth. This is the standard on the small stem M cup pieces.
#T3	Same idea as the T2, just carried in farther. A dark backbore in the small stem configuration. Standard on small bore ML.
#T4	This backbore is very open. Standard symphonic set-up for the ML and L cups in large bore.
#T5	This is the most open, and darkest backbore. I use this backbore to balance the large bore M so as not to be too aggressive or edgy.
#BT	​The standard bass backbore. As you would guess, very open, but set-up to balance well with the funneled throats to aid in a consistent and focused feel.
