I built a Precision-style bass, AND I JUST LOVE IT! It features flatwound strings and a Seymour Duncan Antiquities p/u.
For you gear heads: Warmoth left-handed Telecaster bass neck (strung right-handed, but with reverse headstock), ebony board, Fender P Special body (has route for additional (J) p/u, into which I put a hollow pickup cover just to make it look finished). I hadn't used it in a while, deferring to my Epic, until last night when I broke it out, and used an Adamas graphite pick on some songs. It's got the thunk sound!
