Jazz neck to boomy and mushy what's the alternative?

[Demanic]

Was just playing my DXMG with a Jazz n in the neck, clean, through a ss combo. Bolt on neck, Floyd, basswood body. Not boomy or mushy or shrill. I suggest lowering the pickup height first. The sweet spot is a bit lower than you think that it is.

How about raising the pole Screws for the A and D strings? Leave the low E pole flush with the bobbin, then tilt the the pickup via the mounting screws and you will have less boom in the bass. Also try raising the screw for the D pole by one full turn and leave all the others low.
