This instrument review was with a Monette TT 4 L LT mouthpiece. It is a really wonderful trombone to play!' The Holton falls between a Conn 88H and a Bach 42B in sound and feel. The tone is full and rich without being too heavy. I wasn't sure if I would like the 9 inch bell, but it responds very well.
