Slide trumpet?
I own a Jean Baptiste slide trumpet that I purchased from a Sam Ash music store in LA. It's definately not a soprano trombone in any way. It's the same exact pitch, mouthpiece, bell and bore size as a standard trumpet and it's in the key of Bb. Range is a little more limited than a normal trumpet and there was no fingering/slide position guide so I had to figure it out for myself. I use it only for fun as it is not practical for performance.
Reply:I have actually played one before. It uses a regular trumpet mouthpiece and has the same range as the Bb trumpet. I know Jupiter makes one that you could order from Woodwind and Brasswind. The alto trombone is a different instrument. It has a bell about the same size as a flugelhorn.
Reply:Getzen used to make a slide trumpet. I don't know if they still do. It was in the key of Bb and used a trumpet sized mouth piece.
Reply:There was a "Superbone" designed and played by the late Maynard Ferguson. It utuilized both the slide in conjunction with the valves. This was made by Holton. I hope this helps
