I'm thinking about buying a Fender '97 Am deluxe V jazz bass and the guy let me borrow it for a few days to test it out. Although I dig it, I wonder if It would be worth it to make some changes. 1. I have an Aguilar OBP-3 preamp 18 volt...Is it possible to put it in the bass and is that a good move? 2. What pickups would be a good replacement that can give me good growl without sacrificing that good slap tone? 3. Would it be a good move to replace the bridge with a badass bridge V?
