Jazzophone

The jazzophone is a comparatively rare sax-shaped double-belled Bb Trumpet, with a trumpet-like mouthpiece. One bell is left open, while the other bell uses a harmon mute with a stem on a trigger that produces a "wah-wah" type of effect.

Speculation is that the first was created in 1920, with the first known advertisement for the instrument appearing in a German magazine in 1926, but other musical experts disagree there is another form of jazzophone. Collector "Captain Kazoo" claims to own such an instrument. No specific details besides a picture are given, but it appears to be a kazoo-shaped body with a single bell. The previous mentioned jazzophone was created completely separate of the "Kazoo" model. The only common link is the name.
