Description

The early 1900s look is reborn! Long-awaited replacements for the A-style tuners used by Gibson and other makers from the 1910s until 1925.

The "worm gear under string post" configuration and wider vintage post spacing is ideal for restoring older mandolins and improving their tuning, and for making modern replica instruments more authentic. Our relic nickel finish version has the right look to complement vintage hardware.

Special note about string spacing! These tuners feature historically-correct (1910s-1925) .931" string post spacing. This is wider than standard .906" (29/32") spacing. Please measure your mandolins string post spacing before you order.

Steel baseplates feature the original early 1900s shape, incised "tread stripes," and vintage-style square riveted worm supports.

Each set includes:

• Pair of 4-left, 4-right tuning machines
• Press-fit peghead bushings
• 1920s-style mounting screws

These replica tuners have special spacing for vintage Gibson and other makes before World War II.

Installation Tips

Mounting screws: Pilot holes required. Installing delicate screws into hard wood requires great care and accuracy. We highly recommend the a 3/32" / .094" / 2.39mm bit for the pilot hole before installing these screws. Lubricate the screw threads with cutting lubricant (also wax or a bar of soap) to reduce friction and help them thread properly.
