I obtained this on this site before and it served me well for a while, but I'm putting it up for sale because I've changed mouthpieces. No returns or exchanges, please. Below is the original product description: This is a screw-down ligature manufactured by the Conn company around the 1920s. It's for alto saxophone and has a thin gold plating. It was originally quite warped, but I had a repairman straighten it. It may be difficult to see, but the left half has a slight vertical distortion (I was told it was difficult to fix it further). Despite the above issue, there are no concerns when using it, and the screws are thin, and it's handmade with high-quality materials. Compared to Selmer's genuine ligatures from the 50s onwards, it gives a brighter, more soloistic, and more flamboyant sound. It's loose on Selmer S80 mouthpieces, and fits slightly thicker mouthpieces like vintage Soloist, Vandoren, and Meyer. It might work with Concept mouthpieces, but the compatibility isn't very good.
