M-120 A-model Mandolin Tuners - 2 planks (4+4) - Nickel

I ordered these for my 25 year old Samick mandolin that I keep around the house. They perfectly fit the holes, and I didn’t need the bushings that were included. They look great on the mandolin, and they work fine for my purposes. A couple of them are a tad stiff, but they don’t seem to slip.....all in all, it appears to be $25 well spent!

My son-in-law brought me his grandmother’s mandolin to look at. Well the nut was broken, bridge warped and tuning machines were a mess. This mandolin was far from a high end mandolin but has high family value. Nut repair, no problem. Bridge, well that took some thinking but corrected. It wasn’t until I restrung the mandolin that the machines showed their true issues. Old cheap machines had no bushings. This causes the sting pegs to tilt and be very hard to turn. 2 of the buttons exploded on me when tuning. My first thought was to repair the buttons with new. Well the cost of new buttons and shipping was more than these cheap machines. Yea, they are far from being high end machines but again this is no high end mandolin. Once I put the new machines on it, it really made a huge difference on the mandolin. Easy to turn and tune now.Things to know.The mandolin I worked on only had these plastic disks glued on the headstock to support the pegs. They all were broke free of the headstock and only a decoration. I do work with string instruments in my spare time so I have a few tools, some specialty tools. Being that this mandolin didn’t have bushings installed I had to drill to counter sink the new bushings. This can be tricky if you don’t have the tool. This was the only mod I had to do to install the machines. They worked out great and tune very smoothly. This was an easy fix and easy justification to pull the old machines. Worth the $16+ for the new ones.

Friend had broken tuners. Did the job. Grovers are better but 4-5 times more money

I used these to replace the tuners on a 'tater bug mandolin. The original tuners were hard to turn, and when one of the gears broke, replacement was necessary. The peg spacing matched. The mounting screw placement was "close enough", and the bushing on the pin helps keep things aligned so the mandolin is now easier to tune. A little more information on hole placement and dimensions would have been nice.

it was the wrong one with the wrong space between the pegs,

I needed to replace the machines on a 50+ year old Kay mandolin, whose tuning knobs were literally falling apart. Was very concerned that what I ordered might not fit, but the measurement seemed to check out at 23 mm, which is still the standard spacing. The M-120 appeared to be a good quality and price point for what I needed. They arrived promptly and in good condition, and I was delighted to find that they fit perfectly. No need for the supplied bushings - the posts as they came fit snugly in the holes, and I was able to fit it with strings, get it tuned up, and it's holding its tuning very well (especially for new strings).

Very pleased with these tuners. They are a nice upgrade to my Rover RM35 mandolin. They look good, hold tune great and didn't break the bank. Worth the investment

These tuners were an ideal replacement for my 1970's era harmony mandolin . The ferrules were wrong for the hole so I just kept my old ones . They work well and even the screw holes match . You can buy a lot of tuners cheaper than these but these are the best I've found for the money .

The tuner is good, perfectly set on the old neapolitan mandolin, 23mm between pegs.
