Guyker Locking Guitar Tuners — 1:18 Sealed, Black (6 In-Line, 3+3 or 7-String)

Guyker locking tuning machines lock each string at the post with a knurled thumb wheel on the back, so you need fewer wraps, string changes go faster and the guitar stays in tune through heavy bends and tremolo use. The precise 1:18 sealed gear makes fine tuning easy, and the black finish suits dark or vintage-style hardware.

Highlights

• Rear locking: a thumb wheel clamps the string inside the post for better tuning stability.
• 1:18 gear ratio: fine, accurate tuning with sealed, lubricated gears.
• Four layouts: 6 in-line (6R or 6L), 3 per side (3R3L) or 7-string (4R3L). Choose above.
• Easy swap: made for modern 10mm peg holes with a 45° fixing tab; screws, bushings and washers included.
• Fits ST, TL, SG and LP-style headstocks with matching hole sizes.
