Well.. between the original Bi-sonics, and the Darkstar re-creations, and then the Chi-sonics, and then some of these boutique options (the Nusonics on one hand, Roger Daguet's neo-Darkstar on the other), I really like this resurgence in a wide spectrum passive pickup! I would love to understand the physics of it, but they really seem to be responsive as hell to dynamics in a way I've never been able to coax out of any of my other basses, and I've had Ibanez, G&L, Fender.. I mean, I've never dropped ten grand on a custom Fedora with a Pope pre-amp, but that's just not how I roll.. and from what I hear from gear demos, I'm pretty happy with what I've got. Not that I'll let either of my JS's keep me from reeeeeeeaaally wanting to demo one of these fabled Newark St Starfires.
