Here's what Lollar say about the Jazz Bass Pickup Set:
Featuring vintage output and scatterwound coils for superior tone, the Lollar Jazz Bass style neck pickup offers a full, clear sound. We use RWRP technique for humbucking when combined with the bridge pickup. Wax potted and made with Alnico 5 magnets.
