So I was searching through craigslist the other day and found a black and gold Jupiter pocket trumpet for $200.00, brand new. I wanted one 5 or 6 years ago whe they sold for around $400.00 but thought that was a bit much for a toy. It arrived today and I tried it with my Monette B6 and it was kind of squirrelly pitch-wise. I then tried my B 4 Flumpet mouthpiece and it was a nice match. My fifth, sixth, and seventh grade band students will love it. N plus one strikes again! Anyone else have any history with this instrument?
