Hey all - I bought a Fender American Jazz Deluxe V fairly recently. After playing for some time, I feel the sound is a bit flat with the active electronics on. Or put a better way, stale. I'm thinking of putting a nicer pre-amp to give it that extra oomph. However, I know absolutely nothing about aftermarket bass components. Would I need to replace both the pickups and pre-amp to get more out of the bass? Also, what would you recommend for someone that plays mostly rock, funk, and metal? I like a nice warm sound when I'm running around the neck, but I also like to get it nice and punchy at times as well. Thanks!
