Re: Keilwerth SX90R
I own a SX90R tenor and I'm in love. People have problem with the rolled tone holes, but I find no issues with them. The ergonomics are different than your typical sax, but I like them better.
But the REAL winner is the sound. Big, fat, rich sound. I wouldn't trade it for anything else. But they aren't for everyone though, so try it out and see.
I highly recommend them.
