A-flat clarinet, a Crampon R13, was given to me by a professional musician acquaintance. It's in good condition and plays without issue. I think it looks pretty good for a used instrument. There's a sense of use due to aging. However, if you are concerned about details, please have it adjusted yourself. The serial number is in the 380,000 range. A folding stand that fits in the bell will be included as a bonus. The case is likely a genuine Crampon case. I'm hesitant to sell such a good instrument, so I may withdraw the listing.
