Paul Denman is my benchmark when it comes to Stingrays... his tone with Sade when I saw them live was thunderous. I don't really get the Flea tone chasing... but agree, Flea will always, for me, be associated with that MM pickup in the sweetspot... no matter what piece of wood or carbon hybrid it is attached to. I think the appeal for Fender Flea basses with the MM setup would actually limit sales to the die hard Flea fans... whereas the stacked knob jazz that is currently up for grabs is appealing to a far wider ranger of players - both Flea and non Flea fans. Interesting to see what Fender do... but I suspect they would build you a Flea bass as above... if you go via the custom shop... otherwise, just get a body, have it routed accordingly and painted and stick a Fender neck on it. Job done.
