Characteristics - The 4.5G is intermediate in size between a Bach 5G and 4G. The cup is the same depth as the 5G, but the diameter is slightly larger, giving a roomier feel. It is an excellent choice for someone wanting a slightly larger mouthpiece than the 5G for large bore tenor trombone without going all the way to a 4G. The 4.5G also makes an excellent euphonium mouthpiece. The 4.5G is available with a small shank or large shank .275 throat.

Material - These mouthpieces are made from Delrin plastic. Here are some of its characteristics:


      • 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.


Acclimatization - Acclimatization time varies, but most players find they have fully adjusted to the new rim shape within a few days. Most players are able to alternate between a Wedge rim and conventional rim, although the vast majority of players will convert all of their mouthpieces to the Wedge design because of its obvious advantages once they have adapted. We do offer discounts to players who need to purchase a number of Wedge mouthpieces for various instruments.
