best passive humbuckers?

Status graphite.

They do standard EMG sizeand also MM P and J

 

I absolutely love my P that has been modded with Seymour Duncan SSB4's.

Hard to describe but they totally woke up the bass. Seriously, a GREAT humbucker.

 

The most aggressive humbucker that I know of is the DiMarzio X2N-B. I have three basses with them in it, a Fender Squier Bullet in a Rick pickup setup, a Kawai FIIB in a P/J pickup setup, and a B.C. Rich Virgin bass in a Musicmaster pickup setup. The Fender has the most flexable setup, Neck pickup w/series-parallel-volume options and P pickup w/series-single-coil-parallel-phase-volume as well as master tone options. The B.C. Rich has the simplest, pickup in series-volume-tone. The Kawai has series-single-coil-parallel-volume-tone options on both pickups. Cheers. ;^D.

 

the g&ls are the most aggressive i've played, but they are mfd
