Bass Trombone and Euphonium mouthpieces

EUPH series
Euphonium mouthpieces, can also be used for occasional doubling on bass trombone


These mouthpieces are sort of a cross between my tenor and bass trombone designs, with some aspects of each. The "interface" where the rim and cup meet is larger than the XT interface, and I use bass blanks because they need the larger outside to accommodate the larger inside and the threads. The end result is a more open feel and sound, that works very well on euphonium, and is just open enough to be a comfortable bass doubling mouthpiece for tenor players.
The rim shapes are identical to my tenor trombone rims, regular and narrow.
If your mouthpiece sits right at the bottom of your nose, get a narrow rim.

Rims:
EUPH 100 and N100 (25.4 mm)
EUPH 101 and N101 (25.65 mm)
EUPH 102 and N102 (25.9 mm)
EUPH 103 and N103 (26.16 mm)
EUPH 104 and N104 (26.4mm)
EUPH 105 and N105 (26.67 mm)
EUPH 106 and N106 (26.92 mm)
Finishes available: S-silver, G-gold, L-Lexan (polycarbonate plastic)
Rim contours available: Standard, and N (narrow)

Cups:
EUPH H - shallower than a 51D or BB1, for more definition
EUPH I - similar in depth to a 51D or BB1, but with the EUPH series larger rim sizes
EUPH J - most popular in the EUPH series
EUPH K - a deeper cup for a darker sound

Small shanks: (for small shank euphoniums)
4 - most popular backbore for small shank euphonium
5 - larger backbore, more open, for a bigger sound

Medium euphonium shanks: (for some Besson, Willson, and others)
6E - for medium-shank euphoniums, E taper fits medium-shank Bessons and Willsons;
6Es - a slightly smaller taper to go in farther, works better for some older Bessons

Large shanks: (for large shank euphoniums)
8 - standard large shank backbore
9 - larger backbore, for a bigger sound on larger euphoniums

Notes for ordering shanks: The letter on the shank must match the letter on the cup: for example, a standard large shank for a J cup is a J8. All shanks are intended to fit into the receiver 1".



SB series: Smaller Bass trombone rim sizes
and shallower cups for doubling on Tenor Trombone or Euphonium

Rims:
SB 105 (26.7 mm)
SB 106 similar to Bach 2G, Wick 2NAL (26.9 mm)
SB 107 (27.2 mm)
SB 108 similar to Bach 1.5G, Schilke 58 (27.4mm)
SB 110 a little smaller than Bach 1¼G, (27.9 mm)
Finishes available: S-silver, G-gold, L-Lexan (polycarbonate plastic)
Rim contours available: Standard (narrow), and Wide (tenor rim shape)

Cups:
SB C medium-shallow, for doubling on small bore trombones
SB E medium, for tenor doubling, about the depth of a Bach 6½AL
SB G medium-deep, best for doubling on large bore tenor or euphonium
SB I shallower than Bach 1½G, for bright bass sound or tenor double
SB J similar to Bach 1½G or Schilke 58, most popular in the SB series
SB K similar to Schilke 59, Bach 1¼G, a deep cup for these rim sizes.

Small shanks: (for small tenors, altos, and small shank euphoniums)
alto S - backbore for most Eb alto trombones, slightly smaller taper than tenor to go in farther
alto - backbore for Eb alto trombones with normal tenor taper
2 - backbore for .485 to .500 bore trombones
3 - backbore for .508 to .510 bore trombones
4 - backbore for .525 bore small shank trombones, and euphonium

Medium euphonium shanks: (for some Besson, Willson, and others)
6E - for all medium-shank euphoniums, E taper fits medium-shank Bessons and Willsons; others on request

Large shanks: (for large shank trombones and euphoniums)
8 - standard large shank backbore, best design for most trombones and euphoniums
9 - larger backbore, especially for dual-bore large shank trombones

Notes for ordering shanks: The letter on the shank must match the letter on the cup: for example, a standard large shank for a J cup is a J8. All shanks should fit into the receiver 1". Large (bass) shanks: Bach, new Conn, Edwards, Holton, Shires, and Yamaha tenor and bass trombones, and all large shank euphoniums, use the standard large shank. Older Conn and Blessing large tenor and bass trombones require a different taper - specify Conn shank for proper fit. King duo gravis, 7B, 8B, and Benge 290 can use standard, but sometimes need a specially tapered “K” shank for a better fit.
