Delrin one-piece mouthpieces have been discontinued and will only be available while supplies last.
- Inner Diameter: .660 measured .04 inches into the cup.
- Outer Diameter: 1.104
- This mouthpiece has an extra-shallow V cup which has a cup volume similar to a Wedge S cup, but it is divided between an extra shallow upper cup and deeper V shaped lower cup. It resembles a Parduba, Callet Superchops, and other modified V shaped shallow cups. The result is more secure slotting in the upper register and a more open blow. The Lead V cup with a #27 throat feels much like an S cup with a #25 throat. It is an excellent mouthpiece for commercial lead and also for pit and pops. This is also a good mouthpiece for Piccolo trumpet if one prefers a shallow cup.
- Backbore: This mouthpiece comes on a small backbore.
- 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.
