DEPENDING ON THE MODEL...
- some will be one-piece
- some will be threaded to accept any Sellmansberger stainless rim
- some will be offered in both standard and euro shank sizes
- OG Ultimate (biggest seller - so far - of the brass models, plays most any contrabass tuba well...very CLEAR sound on 4/4 - 5/4...CLEANS UP and DEFINES the sound with 6/4 instruments)
Here is this mouthpiece on a huge BB-flat tuba (6/4 rotary, Holton-345-sized bell, and .835" bore through the 5 rotors)...
- Sellmansberg II (Helleberg II / L-30H style cup ...This is a very popular cup-style...This is my effort to make is something that I myself might consider using (rim/throat/back-bore) with this style of cup. I've observed that this style cup is one of the few that will play slightly flat-natured contrabass tubas up to pitch (without cutting the instrument).
Shallowberger - This is a mouthpiece with a cup depth significantly shallower than the thought-to-be-shallow TU-23/C4 cup depth. Additionally, the throat size and exit bore would both be considered ~NOT~ large. This is an ideal mouthpiece for an F cimbasso as well as for VERY small tubas (such as vintage .625" bore E-flat tubas, and other very small tubas). It's also an EXCELLENT "Berlioz" mouthpiece (for tuba players who use their F tubas to play Berlioz overtures, symphonies, and other Berlioz-composed ophicleide parts using their F tubas. (I have a video clip released of - NO PRACTICE TIME INVOLVED - running up "the lick" in Symphonie Fantastique with this mouthpiece.
Symphony - We also have a THREADED FOR RIMS ONLY (no one-piece version) silver-plated brass "Symphony" cup "underpart" (cup/shank). and this is ONLY available in a "P" shank (in-between standard and euro - a handy shank size for owners of many of the models of B&S-made contrabass tubas...and (if crafty) these shanks can be "home-sanded" down to standard shank if desired.
