    Is a Frumpet different than a Bb Bass Trumpet?.......please explain all differences. If the Frumpet is in a different key, can tubing be added or cut away to turn it into a Bb instrument?

    The Frumpet (made by Getzen) is in the key of F, it came out in the late 60's or early 70"s.
    It's main use was as a marching french horn, very popular in college marching bands back in the day. I don't kknow if you could convert one to Bb.

    Why would you do that?

    Having a frumpet sounds cool to me!

    Conversion to Bb would entail adding a considerable length of tubing, as long as all 3 valve slides plus another 1st slide (7 semitones), to drop the pitch a 5th, or removing equivalent of 1st and 3d slides to raise it a 4th (5 semitones). Then, each slide would need to be resized to yield 2(1st), 1(2nd), and 1.5(3rd) semitones of change relative to the new Bb fundamental (actually 2nd partial - "C" below the staff).

    So quite a bit of mod would be required and is probably not practical. This is one reason that horns which have two "selectable" keys, like A/Bb or D/Eb, only span a single semitone of change. Valve slide adjustments from one key to the other are relatively small.

    Transposing from F to Bb isn't so difficult that you couldn't just use the Frumpet as it is.

    Just one quick warning, crowmadic:

    If you decide to convert you frumpet in any direction, the risc is very big that you´ll end up with an instrument that is not as good as the original. Intonation, slotting all sorts of things may lost in a process that you´ll have no controll over.
    I think you should keep the frumpet and get a good, cheap trumpet instead!
