Otto Link Super Tonemaster Tenor 5

I've read about this mouthpieces not being precise and symmetrical, it is absolutely true! there are not 2 of them that are the same, the ligature is a little bit twisted and asymmetrical, the reed doesn't sit perfectly in the table and it takes a bit of time to adjust in place.
All this being said, Its my mouthpiece of choice at all times, produces the vintage jazz sound I was looking for and is easy to play once the reed is in place, and of course it looks gorgeous on my sax, its a piece of jewelry.
I'm no STM expert but I feel this mouthpieces have always been like this, and I don't think it would produce the sound I want if it was perfectly symmetrical like a modern machined mouthpiece.
Chinese made 30 euro metal mouthpieces are perfectly symmetrical and sound modern and fantastic, get one of those if that's what you are looking for, I also own a few.
