YCR-333s Serial No. 001605 Likely from the late 1970s to early 1980s. There are no noticeable dents, and the valve work is excellent. I personally used brass valve guides, but the original plastic ones are also included. Although it's vintage, it has no quirks, and the pitch and responsiveness are outstanding, as expected from YAMAHA quality. I am selling it because I have changed my main instrument. A mouthpiece is not included. Please understand that this is a used item before purchasing.
