With a rich dark symphonic sound
Designed for the player whose needs are not met elsewhere, the Pro-Line Concert Hall Series Bass Trombone Mouthpiece affords enhanced projection, even timbre from ppp to fff, and the same great intonation throughout all registers that Marcinkiewicz mouthpieces are famous for. These mouthpieces are optimized to give the player the best efficiency possible without compromise.
The patented Pro Line Concert Hall mouthpieces have a unique exterior design that offers optimal nodal enhancements by placing integral vibration dampers in specific, calculated locations. The net result is a mouthpiece that gives an extremely stable center of pitch, allows unprecedented dynamic levels without distortion, and provides a rich dark symphonic sound without adding the mass of a traditional heavy mouthpiece.
