Product Overview

The 98C is another mouthpiece that falls into a category of sizes that is a bit complicated to sort out due to inconsistencies in Bach rim sizes. It is the best choice for a player using a Bach 7C. It is also similar to a Bach 11C, with a slightly smaller ID.

Confusion arises with these Bach sizes because the Bach 11C actually has a larger cup volume than the Bach 7C, and nearly identical to the 6.75C, depending on the specimen scanned. The inner diameter of the 11C matches the 7C at about .05 inches into the cup (where we take our mouthpiece measurements). Below that point it is smaller, and then larger than the 7C a bit deeper into the cup, as shown in the profiles. 

There is enough overlap in the sizes of the 6.75C, 7C, and 11C that one could easily pass for the other if the mouthpiece was not labelled. The main difference is rim shape.

Available with a .240 inch throat and a larger .250 throat for a more open blow.  Stong players will get a bigger sound with the .250 throat, provided they have the air support required.

Material - These mouthpieces can be made in either Delrin or Acrylic plastic. Here is a comparison of their characteristics:

  • Delrin:
      • Feels softer on the chops because it has more give than metal. This is a great advantage for players with braces.
      • Not as slippery as silver, giving more grip.
      • Added grip makes Delrin mouthpieces feel smaller than their metal counterparts with the same size designation.
      • Not as smooth as metal, so some players may feel slight chop irritation for the first day or two while they adjust.
      • More comfortable to play in cold weather because they feel warm on the chops.
      • Plastic mouthpieces are more responsive than brass, making soft entries more secure.
      • Articulation less crisp with less point at the front of the note compared to brass.
      • Darker sound than brass.
      • Less core in the sound compared to brass.

    Acrylic:
      • Feels softer than brass but less soft and Delrin on the chops.
      • Less slippery than metal but more slippery than Delrin.
      • Grip intermediate between Delrin and silver.
      • Feel slightly smaller than the metal counterparts.
      • Smoother than Delrin, very similar to silver.
      • Comfortable to play in cold weather.
      • Responsive to soft articulation.
      • Articulation is clearer than Delrin, very similar to metal.
      • Sound is slightly darker than brass and brighter than Delrin.
      • More core in the sound than Delrin, but not as much core as metal.
