Yes, I've heard the Lulls - great pickups - as are the Thunderbuckers and the ones in the Vintage Pros are really good, too. It's all quite recent that there are good reproductions available. For a long time it was just the originals and a small run of copies made by Chandler in the late 70's.
Nice bass!
I actually thought the original pickups sounded good too, different but still good, I just wanted chrome pickups instead of black. I don't know why they put black pickups in them, I like the look of the Epi T-Birds better with the metal pickups. I like your bass better!
