A pre-slotted bone nut for a full-size classical guitar, the part you want when the original nut has cracked or a slot has worn deep enough for an open string to buzz. It measures 52 mm wide, 6 mm thick and 9.2 mm tall, with six straight-cut string slots and a flat bottom. Measure your existing nut before ordering, since 52 mm is the common classical width but not the only one, and expect to dress the slots and top to suit your action. Part number VGP50.
