3left/right, L5 button, satin chrome guitar tuners from the Gotoh SG-510 series. All tuners of this series are equipped with some Gotoh finesses. Using the Lubri-Plate process, all contact surfaces in the gear are permanently coated, eliminating the need for traditional oil filling. The end result is an incredibly smooth and durable mechanism. With the Rock Solid shafts, a much higher tuning stability is achieved, as they sit in the housing so free of play due to their design that wobbling is avoided.
