I bought a very clean Bundy Special a few years ago at a music store that had it listed as a student Bundy saxophone. I knew immediately that it was a Keilwerth stencil horn so having my mouthpiece with me I gave it a blow. Huge, thick tone is what I heard and I bought it for about $450.00. What are these saxes worth?, soon after I bought the tenor I bought a Couf Superba I alto which I like even more because of the improved key mechanism. I was thinking of selling this Bundy to fund a Couf tenor or used SX 90. One question, are the rolled tone holes soldered rings on the old Keilwerth also? Anyway, I really like the big tone of this tenor. Thanks in advance for any responses.
