The description below really nails it. I had these in a Fender Am. Deluxe for awhile...(have to modify the pickguard a little) and they sounded great. I'm just sort of "over" messing around for the time being, so I'm clearing out my parts bin.
These are $296 plus shipping on bestbassgear. I will let these go shipped USPS for $150. CON USA.

JSBC5 HE - Twin Coil In-Line Humcanceller
This ultra slim "twin-coil in line“ humcancelling soapstick bass-transducers are precision engineered to bridge the gap between two different schools of basspickup design. The tightfocus and pristine harmonics of a classic single coil, but fully humbucking.
Length = 105mm (4.13"), Width = 19mm (.75")
