These are the G66CBJB dual coil narrow soapbars that are a direct drop-in replacement for pickups in the Yamaha TRB series 6-strings, or other basses with a similar size pickup. Dimensions: 5.52" (140mm) long x .093" (24mm) w x 0.8" (2.8mm) thick. Sensing width: 100mm. Wiring is a 2-wire (ground/hot) configuration. They were barely used - I'm offering them up because I sold the bass that they were in with the original pickups reinstalled. $140 shipped within the continental US Please start a conversation if you have any questions, since I may not check this post often for replies. Paypal or Venmo are ok for payment, and no trades at this time.
