How to order
CB series: ContraBass
trombone and Cimbasso
very limited availability

CB 120 similar size to Josef Klier T6, Wick 4L (30.5mm)

Standard CB rim contour is the same width as my tenor trombone standard rim, but more rounded on the outside. Finishes: S-silver,
G-gold, L-Lexan (polycarbonate plastic, not always available)
CB G shallow, for euphonium with a CB rim
CB J medium-shallow, for peeling paint with a cimbasso
CB L medium, for cimbasso, or small tubas
CB N medium-deep, for cimbasso, contrabass trombone, or small tubas
CB P deep, will hold a single rosebud
Correct choice of shank and backbore will improve centering, intonation, and sound.
Contrabass trombones and Cimbassos (Cimbassi?) may have either a bass trombone shank
receiver or a tuba shank receiver. For best results the shank should fit into the receiver
1" to 1?" and not wobble. For shank information see LB series and TU
series. Different tapers and sizes are available if necessary.
Professionals using the

Shanks: The numbering system for shanks is completely new:
First letter: indicates the cup letter that the shank is made to fit
Second letter: the key of tuba that the backbore is intended for. F is for EEb or FF tuba; C is for BBb or CC tuba
Third letter: the outside taper of the shank
Example: PFAm = a shank for a P cup, backbore designed for FF or EEb tuba, with an American shank
Usual taper choices: (see others below)
Am American shank taper
M Medium, halfway between American and European, also for older Mirafones
Euro European taper
Shank sizes and tapers: for best results shank should fit into the
receiver 1 to 1? and not wobble
xS extra small, for older Besson and Boosey & Hawkes (similar to
bass trombone shank)
Am Standard American taper, labelled either Am or no letter (same as PT small S shank, Wick L shank, and
many others) fits most Besson, Bohm & Meinl, Conn, Holton, Jupiter, King, Martin,
Marzan, Meinl-Weston smaller models, Musica, Olds, Reynolds, Yamaha smaller
models, York smaller models
M fits most older Mirafone 184, 185, 186, 188; also fits some other European
tubas. Halfway between American and European - can be used as an all-purpose shank for multiple horns.
E European (same as PT normal), fits most Alex F tubas and some
Cs, Amati, B&S, Cerveny, Kalison, Kurath, Meinl-Weston large models, Mirafone
191, Nirshl, Perantucci, Rudy Meinl, Sanders, VMI, Willson, Yamaha larger models, York
large models, and other large receiver tubas
H Hirsbrunner (slightly larger than E shank), fits most Hirsbrunners,
or use E shank
