I'm thinking of buying a Jackson kelly but i have one small problem. Is there a difference between Duncan Designed and Seymour Duncan pickups? Or are they just the same?

If you zoom in , you can see that this kelly has duncan disigned pickups

this one has seymour duncan pickups

Difference or not?

It's just an old picture. Modern Jackson KE-3's come standard with Seymour Duncan pickups.

Duncan designed pups are just Chinese made copies of actual Duncans with inferior quality and sound.
