Delrin trumpet tops have been discontinued and will only be available while supplies last.
- Inner Diameter: .680 measured .04 inches into the cup.
- Outer Diameter: 1.134
- Cup Depth: This mouthpiece has an MDV (Medium Deep V) cup, which is similar to a Bach 1 1/2 C or 5C, Warburton MD, regular Schilke, or Yamaha C cup, but it has a slightly more V shaped transition into the throat. This cup produces a large, dark orchestral sound, which is made a little darker than the MD cup by the extra V shape.
Backbore: This top is best used on an ML (Medium-Large) backbore which can be purchased here.
- 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.
