Best I can tell, these pickups have been discontinued for awhile. Huge, warm, clear tone from the combination of ceramic and steel magnets and X preamp. The warmth is evident versus the typical J5 set...I'd say these are more vintage-voiced, as much as an active EMG pickup could be. I bought these from EMG a few months back and had them installed in a bass for about a month. Bridge (L) pickup is 4.1" long, neck (S) pickup is 3.97" long. Asking $75 shipped CONUS, PayPal/Zelle. Thanks!
