Inner Diameter: .665 measured .04 inches into the cup.
Outer Diameter: 1.119
Cup Depth: This mouthpiece is designed with a modified V cup that has been optimized for use on a rotary trumpet. The upper part of the cup is similar to the MD or MDV cup, although not quite as deep, and the lower part of the cup has a more accentuated V shape compared to the MDV. It produces a silky, dark tone when played at low to medium volumes, and the desired brilliance and projection at higher dynamics. This mouthpiece is very stable and forgiving, and despite the rotary trumpet designation also works very well as an orchestral or jazz mouthpiece.
Backbore: This top is best used on an ML (Medium-Large) backbore which can be purchased here.
Wedge Generation 2 Line - The Generation 2 trumpet mouthpieces are designed to incorporate the advantages of the Wedge rim and oval cup in a mouthpiece that is very comfortable and easy to adapt to from a conventional rim. The rim is slightly wider than our original Standard Brand rims. This mouthpiece has our new Double Oval Cup (DOC). The diameter of the rim and cup in the vertical dimension is 10/1000 of an inch larger than it is from side to side. This means that the oval shape of the Wedge rim is continued down to the base of the cup where it joins the throat. The DOC design, found only in Wedge mouthpieces, provides the added efficiency of a smaller mouthpiece with the big sound, clear attacks, and flexibility of the larger mouthpiece.
Material - These mouthpieces can be made in either Delrin or Acrylic plastic. Here is a comparison of their 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.
Sounds darker than brass mouthpiece when used with brass or stainless steel backbore.
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.
Sounds very similar to brass when used with brass or stainless steel backbore.
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.
