Golden Age Restoration Tuners for A-style Mandolin

About This Item

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.

"People who build replica instruments or who do restoration or repair work are just going to love these."
—Frank Ford, vintage instrument repair expert

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 mandolin's 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

Gear ratio 15:1
Bushing diameter .283" (7.19mm)
String post diameter 0.236" (6mm)
String post spacing Early 1920s .931" (23.65mm)

These replica tuners have special spacing for vintage Gibson and other makes before World War II. Please be aware that our standard spacing drill jig will not align accurate holes for these tuners.

Installation Tips

Bushings: We recommend the #2066 Bushing Reamer (.290" diameter) to cut a clean, accurate counterbore for a professional job. Fit the press-fit tuner bushings correctly so your tuners will work smoothly.

Mounting screws: Pilot holes required. Installing delicate screws into hard wood requires great care and accuracy. We highly recommend the #1714 Depth-stop Drill Bit (3/32" 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.

Careful With That Bushing Eugene

(Customer's Reviews)

I have a Gibson 1923 A-3 mandolin and a 1918 H-1 Mandola. Both were getting impossible to tune so I decided to replace the tuners. I kept the old ones so If I ever part with them down the line, they will remain original. I wanted Waverly's but with the age of both my instruments that proved impossible due to the spacing. I wanted to preserve the instrument's integrity so I purchased the Golden Age machines for both. All was fine and dandy but for the included bushings which were a tad too big. I made the mistake of trying to force them and ended up cracking the head stock due to the compression pressure of the new bushings. I know it would have been just as easy to open the hole up a bit but I wanted the originals to fit if needed at a later date.I have since repaired everything and all looks and works fine. All I did was use the original bushings which fit the Golden Age machines perfectly. Everything looks and works like new or like used... but just a warning for you who have similar replacement problems... use your old bushings!!! Peace. Dogman


nice & simple

these tuners fit many prewar restorations for both A mandolins & mando-banjos / i also use them on new mandolins for a retro look and feel / my customers have only praise for their functionality


Golden Age tuner good but could still use some improvement

(Customer's Reviews)

I installed a set on my Gibson A3 whiteface. Relic finish much duller than originals, bright finish quite a bit shinier, but I went with bright. These tuners operate very smoothly before installation but become stiff when the strings pull the posts hard against the insides of the bushings. It helps to wind enough string onto the post so it can be guided down close to the bushing, thereby reducing leverage on the post. It would also help if the baseplates were stiffer. Thicker plates wouldn't materially affect the look, they'd resist distortion better, and help the posts remain upright. As it is, string loading bends them to the point I can see daylight under them between the screws (only a light string set, too). This pulls the gears away from the worms, causing play in adjustment and occasional slippage after tuning.
