Gibson don't publish the tuner hole size or mounting for this guitar. Gotoh's SG381 is fixed with one screw set at 45 degrees to the post, and retailers list it for 10mm holes. The listing we link doesn't give Gotoh's full part number. Take one tuner off, measure the hole and check where the screw or pins sit before ordering.

The AZES40 has a curved 6-in-line headstock, so a 6-in-line tuner set is the correct shape here, not the pointed reverse-headstock version. Hole size is the open question. Gotoh specify a 10mm bore for the SG381 housing. Ibanez's own AZES40 spec sheet lists the stock tuners as split-shaft machine heads, a vintage-style design that normally uses a bore under 9mm rather than the 10mm modern standard, and the AZES40's actual hole diameter is not published anywhere and has not been independently measured. The higher-tier AZ2204 and AZ2402 Prestige ship Gotoh sealed tuners at 10mm, but that is a different tuner design on a different production tier and does not settle the AZES40.

This is the right-handed Gotoh SG381 Magnum Lock-Trad set. Gotoh build a genuine left-handed version of the same tuner, and that is the version this guitar needs.

Layout mismatch: this tuner set is six in a line and this guitar's headstock is three per side, so the set cannot be fitted as sold regardless of peg hole size.
