With all due respect to Bob Brookmeyer and the quite few top professionals specializing in valve trombone the sad truth is that valve trombones most often are played by amateurs, while learning the slide, or by those who don’t make it with a slide. Some players may have a bad intonation on valve trombone, but that still may be preferable to their intonation on slide trombone.
Bob Brookmeyer once showed me his valve trombone. It was a hybrid instrument. The bell was by Larry Minnick (the type that went into production as Conn 100H). The body was a stock Conn customized also by Larry Minnick. There were triggers on the 1st and 3rd slides.
The King valve section, which can be used with 2B and 3B bells, has its first slide placed, so that it is possible to manipulate it with your left hand during playing.
There is an anecdote about why the British Championships for brass band exclude the use of valve trombones:
Aside from the main competition there also are prizes for the best soloists on cornet, trombone, and euphonium respectively. The adjudicators traditionally cannot see the bands and players, as they sit in a box, which only lets sound entering.
Some 140 years ago the test pieces often were transcribed opera excerpts. One year it happened that the same player was called onto the stage as winner of the euphonium as well as of the trombone soloist prizes. The solo euphonium player of a band had picked up a valve trombone after having played the euphonium solo and then had played the trombone solo later in the test piece. That situation caused protests and hence the said rule was introduced.
