Just pulled out from a brand new Lakland 55-01, Played only once to test. Includes pickups and full pre-wired harness and preamp, pots, battery connection, and jack. This is a GREAT OEM system found on Lakland, Cort Curbow and will add depth and flexibility. For a list of basses that will fit these pickups please send me a PM. TRADES Countryman or Radial DI boxes pedals ( run anything by me ) Tascam CD-BT1 MkII bass trainer Monster or Planet Waves instrument cables Levys wide leather padded strap or other padded "comfort" strap Headphone amp NIB strings ( Ernie ball, DR or D'addario ) Cash + / - will be discussed as appropriate. Thanks!!!
