One of the bands I play bought the Jupiter 582 L
I have it at home and maybe I will have it for some months.
I use to play a yamaha 201 and a MW 25.
I also played some time other Jupiters, some Amati (very common(?) here in Azores) and other not so known (and not so good) chinese instruments.
It is very soon to make a close comparisson. But, for now, I must say that I am well impressed with this big Jupiter.
Without doubt the best Jupiter Tuba I ever played.
I will play it for a while and then I will post some feedback and photos.
I would apreciate some feedback from you that have already played this tuba.
Sorry for strange English, still working on that

Thank you all
Antero
