Hey, I have a MIM Fender Jazz bass. I've been thinking about replacing the stock pickups, but I'm not sure what to use. If it helps, I have the bass strung with Fender flatwound strings. I play mainly 50's and 60's music, so I like a good clean bottom end. I've been thinking about using either the Bassline quarter pounders, or the Fender 60's custom shop pickups. Could anybody who uses either of these give me some guidance? I would really appreciate it! Thanks very much!
