Well my Warwick Streamer Stage 1 (four strings) sounds too modern and very growly. I played with EQ but its natural modern tone and aggressiveness still exist. What can I do to get a vintage tone? Something between P bass and Jazz. I'm thinking to put a set of flats LaBella and replace the active MEC P/J pickups with Seymour Duncan Lightnin' Rods. SD characterized them as vintage-voiced pickups.
