I'm saving my money to build a Warmoth fretless J Bass. I've been going back and forth on if I want an active pre-amp on board, active pups or just going passive. Right now I'm leaning toward going passive. I'm looking into Lindy Fralin pups but not quite sure if I want 100% vintage sound; are these pups trully vintage sounding with the same specs, sensitivity and output as an old jbass? Or are they an improvement that really do sound better? If they don't actually sound better then I'm thinking they may not be worth the price (they're pricey). I've also heard about Semore Duncan Atntiquity II's or the regular Syemore Dunans. I also play an American Standard J Bass, a Ric, and Modulus Q5 with active Bartolini pre-amp and Bartolini pups. I just want something a little different. My pup decision is starting to be more overwhelming than I though it would be. Everyone's opinions would be appreciated.
