I just spent hours investigating pickups to put in my Jazz bass to give me a vintage 60's sound. Fralin Jazz pups appear to be the most expensive and are highly rated. Lollars get a good mention. Nobody seems to have a bad word about SD SJB-1's which are less expensive. In at the same price as SD's are the Fender Pure Vintage '64's. Fender CS 60's and other SD models seem to be more modern, hi-fi or hotted-up. At the bottom we have Fender Originals which seem to be less powerful than the rest. As my bass isn't expensive at all, I have decided to go for the SD SJB-1's. Not sure what the bass will sound like as it's a bit of a distressed Frankenstein. And then it dawned on me . . . . Being an old bloke, I remember in the early 60's we played with strange shaped picks mostly. Nobody slapped. So 'vintage 60's sound' and slapping in the same sentence is an oxymoron. Also, the hardware was left on so we didn't play over the pickups. Hence, someone playing fingerstyle above the pickups is not authentic either. I can remember after 1965 Fender's were crap IMO. I sold my '66 Jazz because it didn't sound like a Fender. 70's Fenders were awful so I settled on a '77 Stingray. I might forget about vintage 60's now and just play. I'm sure the SJB-1's will be fine.
