Jupiter JPS-547GL soprano saxophone reviewed at SHWoodwind, December 2015.
"Tonewise, I'd say it's a slightly stiff blow. That's different from 'resistant' insomuch as a resistant horn can still still be punchy and bright...and the Jupiter isn't. My very first impression was that of having a 'frog in the throat' - that slight gritty huskiness in the voice that often heralds the onset of a sore throat or a cold".
"When all is said and done I feel the JPS-547 is a bit of a mixed bag. I'd say the build quality is just about bordering on under par for the price".
...
"when all is said and done, the 547 isn't a particularly joyful horn to play".
My reaction to the above review was:
(1) No thanks for hurting the resale value of Jupiter Soprano 547s.
(2) But that is not my Sop (technical details were different based on photo comparison).
I did take on board Forum posts suggesting the "Jupiter curse" was poor resale value and that that review was not helping resale value. FWIW, I liked the tone of my Jupiter but it is a stiffer blow than my 82Z.
