Re: info on Keilwerth's SX90II
Well, I'm not sure why you care so much about the damn engravings, but I do believe it is engraved. And if not, I don't believe there is anyone that engraves horns besides the manufacturer. I don't think anyone ever asks for that. You should be so wrapped up in cosmetics, but the sound and playability of the horn.
Theoretically, there is no "jazz horn", It's the setup you have(reed, neck, mouthpiece, lig) and somewhat the finish if any you put on it. Some saxes are unlacquered is what I meant by "if any", they tend to be more resonant. Read up on these types of things or something. And I'm sure you can check on a dealer's website and look at it. There's thousands.
