  • 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 small bore tenor trombone without going all the way to a 4G. The 4.5G also makes an excellent euphonium mouthpiece. This 4.5G Small Shank has a .275 throat, but it is also available with a large shank .275 throat.


  • 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.
