Kevin designed the JXB basses to take advantage of what Brubakers offer while not losing what Fenders are fundamentally about which has been why I didn't own one of bigger name boutique jazzes... my Fenders always seemed to do "Fender" better.
My JXB-6 is heavily inspired by my 1978 Fender J. 34" scale, 22 frets. I have dual coils but can switch to single coils that are in the same physical position as my Jazz. What I ended up with is a sonically faithful six string version of my 78, with Brubaker sustain, punch and playability.
I'm predominantly a finger style player, it does that and slap with absolute ease. A hard-hitting finesse instrument.
For a nice round bridge pickup burp I'd go with an Alder body. It'll give you that and still kill slap-wise.
