Anyone tried them? I got six Jim Bau trombones for free many years ago. The trombone cases are very good. I gave away all but one. Tried them all. Playable yes, but valves and slide never works smooth. The mouthpiece seems to be a copy of the Bach 1 1/2g. First try was very good, felt comfortable and sounded ok in my ears. Then I made a recording. Legato was down, attack was down, sound was ok but not full.
It will take a long time for China to take over the trombone marked, Putin can never make it. Don't let Trump destroy my Conn 70h
