Grover F-Style 309 Mandolin Tuning Machines

Grover F-style mandolin tuners are available in two different gear configurations, with engraved die-cast baseplates and 18:1 gear ratio.

Standard 29/32" (23mm) string post spacing.
11/32"-diameter (8.73mm) pegholes required.

Each set includes:
• Pair of 4-left, 4-right tuning machines
• Removable pearloid plastic knobs
• Press-fit peghead bushings
• Mounting screws

Available in two different gear configurations:
#5675 with worm gear under string post (turn the the knob counterclockwise to tighten the string)
#5674 with worm gear over string post (turn the knob clockwise to tighten the string)
Important: These two styles may not be interchangeable on the same peghead. See Specs before ordering.

Tip: Plate-mounted tuners can't work efficiently if the pegholes are improperly drilled. Our Mandolin Peghead Drill Jig ensures precise 29/32" spacing for accurate alignment for these tuning machines.



Use the standard reamer to install these bushings:

Swapping out Gotoh tuners on the Loar M-600

By
(Customer's Reviews)


I have a Loar M-600 mandolin which comes stock with Gotoh tuners. I've had real trouble keeping in tune and getting to proper tune with the strings jumping sharp of what I'm trying to achieve. I decided to try Grovers with a lower gear ratio. I have to tell you that they work great! Installation was easy. The machine holes lined up and three out of the five screw holes lined up. I used the existing bushings and screws. All I had to do was drill pilot holes at each end of the back of the machines in place on the mando scroll. The original screw holes are covered by the back plates and do not interfere with the new holes. The Gotoh machine plates extended a little further toward the nut side of the tuners so you can see a slight impression of the end of the plate in the wood on the back of the scroll. Not a big deal. The tuners are far superior and make tuning to proper pitch a snap. Delivery from Stew-Mac was quick. Money well spent.

Good fit for the Epiphone MM-50E Mandolin

If you are considering these tuning machines for your Epiphone MM-50E I would highly recommend them. Perfect fit, easy tuning & stays in tune unless you bump or turn the keys. I have used them on mine for a month and I love them!

great tuners

I've installed them on my new Eastman, I didn't even had to drill new holes, they really do fit and what's more important, work perfect. Now i'm thinking of replacing the tuners on my Gibson A1 also. As for the shop: super fast delivery, that is how an internet shop should work! thank you! It did not take more than 3 days including German customs after ordering!
