Hipshot Ultralite bass tuners. Set of 4, with chassis and screws. These were removed from a LAKLAND shoreline series bass (assembled in Japan). This is why they are not marked "USA". Please refer to the photos for weight and dimensions. There are no issues with the operation or tuning stability. - One tuner has some paint chipped off (see last photo), but this does not affect its function. - One tuner is slightly stiff to turn due to age, but this does not affect its function. It can likely be remedied with grease or cleaning. These are used items, so please understand that they are sold as-is, and returns are not accepted.
