Yamaha Professional model trombones have long been popular thanks to their quick and agile response, highly accurate intonation, and rich warm tone. The new Pro series have kept all these fine qualities, while adding some design features from our top of the line Xeno trombones. Their broad sound has a well defined tonal core for excellent projection in all registers at any dynamics. The 640 has a medium-large bore for versatility in all musical genres. Both models feature two-piece bells for a quick response. The narrow style slide and medium weight construction provides exceptional playing flexibility.
