[Trombone-l] Don't pull your F slide out too far

Sat Apr 5 21:54:03 CDT 2008

Definitely Doug beat him to it.  And the constant bore design isn't original either.  Earl Williams and Olds figured that one out too.  Those patents were, however, quite interesting, and were exhibited at the 1994 ITA.  Hard to get used to, for sure.

As for the Eb valve and the constant bore, my latest small bas I built for myself has an Eb pull and a constant bore as well.

Sue me :-)
