You want a hex-aphonic pickup with a breakout box like this:

hex-aphonic pickups systems are available from roland, graphtech,rmc,
and a few others
I personally have a roland gk2, gk3,and graphtech ghost lb-63 bridge.
any of those would work with the above breakout box. If your not one
for building a breakout box can be bought, but all the ones i've seen
usually sell for over $300 a piece.
