My main stage bass, a neck-thru MIK Schecter Stiletto Studio 5, came stock with a pair of soapbar EMG HZ pickups and an active 3-band onboard preamp. (I believe the EMG's are ceramic/steel blade magnet humbuckers). Although this setup has served me well, I am ready for an upgrade. I believe this maple and mahogany neck thru bass has plenty of potential waiting to be released by some premium electronics. I've been reading up on Seymour Duncan NYC's, Nordstrand Fat Stack or Big Singles, Bartolinis, and more. I want to find something a step above what I have, a passive high-output pup with deep tone and clarity at low notes. The musical style can get fast and aggressive (no slapping). I downtune every string a minor 3rd, and when I venture below the 5th fret on the B string it's a mud run. A neck pup with the attributes of a P-style split coil would be nice. If anyone with experience in this matter could shed some light I'd appreciate it. And if anyone finds my approach backwards and thinks I should be replacing the active electronics first, I'm all ears. Thanks!
