Designed by Duncan bass guitar large soapbar pickups - info wanted

[bassface101]

Hi, nooby here.
I have a 1999 Jackson Concert CA-4 bass guitar with 2 large soapbar pickups with 'Designed by Duncan' on them. Could anyone tell me information about them, they are close to 115mm long by 27mm wide, 2 screw holes at top, only one at bottom.
Is 'Designed by Duncan a cheaper version under licence of Seymour Duncans? Are they humbuckers or single coils, alnico or ceramic etc. Are these seen as any good? I like the sound I get from them, the active preamp and bass boost offers a very wide range of tones.
I dont think Seymour DUncan do an equivalent size now to these. Possible upgrade if I can find the right size pups.
Photos - The guitar is how it was before I got it, damaged paint job and a loose washer, the instrument has been stripped back to the wood since then!
Thanks Stu

Even when Duncan had their DD webpage up, there wasn't much info on those two particular pups. You could at least look at the bottom and see if you had 101's or 102's. Not sure how useful that is though.
