    This set is laid out three tuners per side, and this guitar has all six tuners in a line on one side of the headstock, so it won't fit. The Kluson 6-In-Line Locking Deluxe Series is a vintage-style locking option in the right layout.

    Why we say this

    The Gotoh SD90-MG Magnum Lock is sold as a three-per-side set for Gibson-style headstocks (retail listings at Amplified Parts and Thomann list it 3L/3R only). This guitar has a Fender-style 6-in-line headstock, so the layout does not fit regardless of peg hole size.
