Gotoh SD91-MGT-05M-CK MG-T Locking Tuners — L6 Cosmo Black

Best for

A vintage-style six-in-line electric-guitar headstock that has been measured for the SD91 MG-T L6 footprint and needs rear-thumbwheel locking tuners in Cosmo Black.

Who should skip

Skip for R6 or 3+3 headstocks, incompatible bores or screw patterns, a different finish/button/post system, or any installation whose machining requirements have not been measured.

Watchouts

Exact configuration code is SD91-MGT-05M-CK: SD91 family, MG-T post, 05M button and CK Cosmo Black finish. L6 is the array configuration. Do not flatten Black Chrome B into Cosmo Black CK, or substitute R6, custom stagger, MG, HAP or HAPM versions. No configuration-specific GTIN is supported.

Likely add-ons

• dimensionally compatible 8.8 mm L6 headstock or correctly planned conversion bushings
• correct mounting screws and bushings
• measurement and installation tools
• qualified guitar technician when drilling or other modification is required

Verify before buying

• Is the headstock L6 rather than R6 or 3+3?
• Are the bores 8.8 mm and adjacent tuner positions compatible with 23.8 mm spacing?
• Does the rear screw pattern match without drilling?
• Are three 18.5 mm and three 20 mm posts correct for the string paths?
• Are the required bushings and mounting screws present and dimensionally correct?
