Grover Vintage Bass Machine Head 142C4 Guitar Tuner

I've used Grover tuning machines before, but was still impressed with the quality of these units. They are well made, smooth as silk and offer reliable tuning stability. They fit vintage size peg holes (~18mm)Installation was done on a new neck so I cannot report on how the mounting holes lined up with old units. I can tell you that the bushings are strong enough to handle being tapped into the peg holes with a brass mallet. I used a 1/16" drill bit to create pilot holes for the mounting screws and that was pretty much perfect.I see these tuners lasting forever. If you want a quality set of vintage Fender style tuners, these are a great option.

Great quality tuners!!! Great price!!

The tuners themselves are fantastic. HOWEVER, The mounting hardware they send with the tuners are garbage. I completely sheared off the head of one of the screws during install. Would otherwise have given a 5☆ were it not for the janky hardware.

I have a right hand Squier Affinity J Bass and the stock tuners were horrible. The handles actually would come off on 2 of them and sometimes you would hear vibration on certain notes at the headstock and it would stop if you grabbed the loose handles. So this upgrade saved this bass from the trash!! I did have to make the peg holes bigger for these to fit. I just wrapped 100 grit sand paper around a socket from my socket set and sanded until I could tap these in place. I had to drill 2 new small holes for each tuner since 2 of the holes lined up and 2 were covered. I had these installed in an hour and a half easily and I was working at a leisurely pace. What a great upgrade these are from the stock Squier tuners! No more vibration and the tuning stays put and is more accurate. The gear ratio was higher on these so it takes an extra turn or 2 for the tuner to make a complete rotation so these are able to tune to pitch without overshooting and I detect no slop in the gears in either direction. I love these!

I put these Grover machine heads on my MIM Fender Standard Jazz bass. The stock ones were not terrible but they were a bit rough turning and seemed to go out of tune more often than on other basses I have had. I am very pleased with the Grovers. They are heavier built than the stock ones and look and feel higher quality with a nice finish and good quality castings. The Grovers feel a lot smoother turning and stay in tune better than the stock heads. Also the Grovers were fairly easy to install and fit well except that only two of the four mounting screw holes on each head fit with existing holes. I drilled two new holes for each and the old holes were covered by the bigger mounting surface of the Grovers. I did not notice a significant change in the sound of the bass. I think that the Grovers are a good value and gave my bass a higher quality look and feel.

I purchased these for my 20 year old import bass. All I had to do was file out the hole where the shaft goes thru. Once that was done I filled in the mounting holes as new holes had to be drilled to accommodate the new machines.Tip: Do not discard the old screws, the ones that come with the tuners are not of good quality. Other than that you are getting a nice product.

I installed these machines on a Squire 50s Vibe Precision bass. fit well with very little modification needed. The bottom screw holes on each machine did not line up but that was expected. Very good quality, solid and smooth tuners

Super smooth and well built! Makes tuning way easier than the stamped fender tuners the bass came with, a worth while upgrade!

Très bonne qualité, la photo ne rends pas justice. Elles en jettent et inspire vraiment confiance. Le mécanisme est vraiment doux et régulier. En plus le prix est raisonable et elles sont garanties à vie par Grover. Un seul petit défaut: le poids, environ 90 g par mécaniques.
