I bought this case for my Ewi 5000, and it's a perfect fit for it. It's branded as a soprano sax case though. I would like to say to anyone who wants to buy this case: DON'T BUY IT FOR A SOPRANO SAX!! This is a way too tight case, and the keywork would touch the case, which is usually what causes the most damage. For an ewi it's perfect, you can even store some cables and you wireless connection buses in there, but don't, for the life of me, put a soprano in there.
