Hello all, I'm currently in the planning phase of building my own bass. As far as the body is concerned, I have a pretty solid plan laid out. I'll be scavenging the neck, bridge, and machine heads from a DIY jazz bass kit, and I'll be buying a slab of poplar to construct my own custom body for the bass. I'm an accomplished woodworker, so that side of the equation isn't something I'm too worried about, but I'm completely out of my depth when it comes to wiring and electronics. I know I want to use Seymour Duncan Dano-style lipstick pups for the neck and bridge, and I also want to add a Seymour Duncan hot jazz stack in the middle. I also know that I'd like to add an onboard active preamp (with passive/active bypass switch), and I want to add a pickup selector switch so I can have all three pickups going, only the lipsticks, or only the jazz stack. My questions are: 1) How many control knobs will realistically be necessary for this build? 2) How would I need to wire this all up to get everything working the way I'd like it to? I'd also love to get some recommendations on different active preamps that you guys think might be good for this build. I've heard good things about Sadowsky, Seymour Duncan, and Tone Monster, but I'd love to hear of any others you guys might suggest. Thanks!
