AH, from Epiphone:
At the heart of this bass is the revolutionary NanoFlex(TM) and NanoMag(TM) pickup combination. Custom-made for this bass by Shadow Germany, these pickups provide a wide range of tones suitable for almost any type of music. Under the saddle, the NanoFlex senses the vibrations of the strings AND the body of the instrument simultaneously. Not a piezo, this exclusive, low-impedance 7-layer element has active electronics and 100% shielding to ensure no sound is lost and no hum is introduced. The NanoMag is located right at the end of the fingerboard - just like in Epiphone's award-winning Ultra-II guitar. Positioned at this sweet-spot, the NanoMag captures all the subtle nuances and harmonics of every string. Like the NanoFlex, it too is low-impedance with active electronics on-board but it features a tiny air-coil, 3 samarium-cobalt magnets and silver-platinum shielding for a hum-free output. Both pickups are controlled by an active electronic system featuring a Master volume, pickup Blend and individual bass and treble controls for each pickup.
Too bad it's 34" scale. If it was 30" scale I would really be interested in trying one out...
