Err neither...he plays on a modified dukoff made by Bobby Dukoff himself that has been changed over the past years but by todays standards its a measurement of a D8. Hes always played on the same dukoff. And sanborn has his own website. He had an old one with interviews (Audio) on it but they made a new website and forgot to add them or something. His specific setup is a Selmer Mark VI Alto (worth $6000), Dukoff D8 with either 2.5 or 3 Java reeds. If you plan on buying a dukoff, GOOD LUCK. I highly recommend having a person that does refacing look at it. Keith Bradbury is very experienced with Dukoffs, but it will probably cost in the $100s...you can email him at his website www.mojomouthpiecework.com
