I have a Gretsch 6119 Broadkaster/Tennessee Rose. I love playing it, and it looks great onstage, but the pickups are mediocre. I'm looking at the TV Jones p'ups, but there's so damn many different ones. What I'd like, ideally, is pickups that approximate the sound of Hagstrom Bi-Sonics. Or vintage P-bass p'ups. Any suggestions?
