Yeap. I'm not sure if I hit the correct page for their current top shelf offering, but this one:
The 52nd Street saxophone is a professional instrument and comes un-lacquered for a truly vintage appearance. It is an exceptionally responsive horn in all registers and produces a big, fat sound with precise intonation. A larger bell and rolled-style tone holes contribute to the sound qualities...
Does not seem to be the same factory as this one:
The Eastman 52nd Street Tenor saxophone boasts a vintage appearance with professional qualities! Responsive in all registers, precise intonation, and a big sound compare to the great vintage horns of the past thanks to a large bell and rolled-style tone holes. The modern construction allows for...
At least not to my eye.
If CLB's tenor is also Taiwan, that's not a knock on his offering to underline this. The Eastman and others from that same factory are being played by top players because they're up to the task. The understanding of this is just not as widespread yet as it's eventually going to be. Taiwan tenors were on par with everything top shelf made prior to the recent improvements (over the last 10 or 15 years) in alloys and fine tolerances (Selmer and some others have upped the ante in those two categories, fairly recently) starting about at that same point. They continue to improve. This isn't as true as China. Some China factories deteriorate over time. IMO no China offerings are on par with Taiwan on the bottom line, but dollar for dollar (China offerings cost about half of what Taiwan offerings do at wholesale, same specs) the proportional value is similar.
But nobody should assume or believe CLB's offering is from China until proven otherwise. China tenors absolutely are up to snuff for professional work, but those professionals are going to be rock and other contemporary/pop oriented players, not "bebop and beyond." To very skilled (jazz) players there are just subtle differences in balance of scale, response and timbre that are not going to be in line with their concept (though they are in line with other types of players' concept). This, however, is mostly applicable to tenor, which is what CLB is playing/showing/apparently-selling. Altos from China can be made more in line with Taiwan altos than tenors can. They are closer in scale-balance/response/timbre than tenor vs tenor. The biggest difference between very good China and Taiwan altos will be subtleties of response -- in particular when attacking and releasing notes. Soprano is yet again a different case, and some very skilled bebop/jazz players may actually prefer China sopranos to Taiwan sopranos. But when it comes to tenor, again, it's very unlikely the offering in question is from China.
