Shires used to be able to convert a Bb bass into an F bass.

Hey Everyone,

Just did some reading around and heard that shires used to do special work to convert Bb bass trombones into F but not into a full contrabass. Not sure if this is true, but if it is does anyone know about this process/know of any existing models of this? Generally just curious about learning about this.

Thanks,
Steve B

Yup, Benn has one. He should chime in.

Once when I was visiting the factory they had an F bass prototype for me to try. All I remember is that at the time it took way too much air for me to play - I was much more of a tenor player and hadn't had much experience with bass yet.
