This set of 3 x 3 Gotoh GB707 6 string bass tuners feature a 1:20 gear ratio for tuning up quickly and accurately. The 'Rock-Solid' string post improves the tuning stability of the tuner and stays strong during bending and tremolo use, special elastic parts eliminate any rattle in the post and transmission of string vibration to the instrument is maximised. The tuners are completely sealed and permanently lubricated through Gotoh's 'Lubri-Coat' technology, a coating applied to the worm gear to ensure better contact between the worm and spur gear wheel, backlash is minimised and durability is increased. 3 x 3 Sets can be used with either right or left handed bass guitars.
