ALAIN TRUDEL REPLICA MODEL The Trudel mouthpiece offers players a big warm sound and a rim and cup size well suited for orchestral as well as solo use. Its deep cup and special rim contour give the sound and feeling of a much bigger mouthpiece while maintaining the secure well-centered high range usually possible only with a smaller mouthpiece. It feels wide for comfort but it s not a chop buster. Also the rim is fairly thick to help endurance. Inside the deep cup is U-shaped but has a V-shape going into the throat. This design makes for a smooth dark tone that blows free and has great overtones. The backbore is shorter than a standard mouthpiece for a quality response in ALL registers.

It is characterized by a full centered tone with a focused core and a brilliant well-defined overtone series. It combines the best aspects of large symphonic style mouthpieces with an ideal amount of outer mass and a carefully designed backbore and throat for improved high range and dynamic flexibility. It is characterized by an even response in all registers and dynamics. As Doug explains: This mouthpiece is designed for the player who wants a big sound as well as flexibility. While I do most of my work on the bass trombone as a member of the Boston Pops Orchestra I also enjoy giving recitals playing in church and doing jazz and commercial work. The mouthpiece works well in all of those situations. I insisted on a centered solid sound that would sound good at 5 50 and 500 feet. And it goes without saying that I wanted a mouthpiece that would play evenly and in tune in all registers. When I say I play this mouthpiece all the time in the Boston Symphony I mean it I use nothing else. Whether it be Brahms Mozart Beethoven Mahler Schumann or Berg this mouthpiece simply works. I m confident that if anyone tries this new mouthpiece it will be the last one they buy.
