Musiclily 4-in-line 4R Vintage Open Gear Bass Tuners Machine Head Tuning Keys Pegs Set Right Hand for Jazz Precision P Bass Replacement, Chrome

Bushings are about 18mm. This is the MOST important measurement about the tuners, and its nowhere to be found in the description.It came with just enough screws (16), but one screw was a different size. had to use another screw from my spare parts.Overall, they're a little stiff, but work fine.

First impression is wow these are made nice, heavy and feel like quality in your hands. Haven't installed yet need to drill hole to 9/16" and screws won't line up. My bass is a Korean squire p bass I paid $30 for it complete, hydrodipped it, put emg and new pots and jack, new bridge and straplocks

Just what I needed - strong, steel. I am using these gears as a starting point for my project. Compact design, strength of the material used make it a great solution for my project.

One of the screws broke off into my basses headstock so buy new screws if you purchase these tuners

They fit perfectly onto my old bass guitar and loved how they didn’t skip as I turned them to tune the strings.

Good value for the money they work really nice however ferrules don’t fit without a little ingenuity on your end.. I used a thin brass to wrap the ferrules so they would press in and stay..

I had to fill the mounting holes with a tiny dowel and super glue. The center piece or bushing was slightly smaller than the the MIM tuner holes and I used 4 “small” drops of super glue to hold and center the bushing in place. Then I carefully marked and drilled new holes. I also didn’t trust the mounting screws and bought new mounting screws from ace hardware.Otherwise, the quality of the tuners were about the same as the tuners that came from the factory MIM jazz bass. It’s NOT an upgrade in any way. This is a way to get black tuners or replace broken or worn out tuners.DO NOT put these on an American fender…Ever! I wouldn’t put these on a new neck either. They work good, they hold their tune, they are a little rough, the paint scratches easy. I used the same tuners with 2R and 2L with a built from scratch and they work great.You are buying these because they are affordable not because they are an upgrade. You want nice tuners… save up your money.

they work - but I don't think they have a quality control team nor should they for the price - seems like they just paint the chrome or "bare" tuners and do not compensate for the thickness of the paint - nor are they anywhere near square - luckily I like to take cheap basses and rework them - they seem to be exact douplicates that you'd see on any bass made in Korea in the late 90's through 2015 ish and my stock pile of the older SX basses made there make these an easy swap when a tuner strips . We all know these are far from great - for the price they are what they are and under tension they hold tuning well for 4-5 years

Bought these for my squire vintage modified jazz bass. They are not direct replacements. The holes don’t line up at all, and I had to drill my headstock to make new holes.Don’t get me wrong they look great and stay in tune well, but if you are expecting a direct match, they don’t, and you will need to do some work.Lastly, I had to use the screws that were on the original tuners as the black screws that this kit come with are simply awful. They snap just by looking at them and I had to drill them out which was a lot of work I hadn’t bargained for.

Beware of the screws. I had two snap off at the head while fitting. Bare in mind I am a trained guitar tech so I knew what I was doing.I also had one head chew up completely.Very soft screws.The tuners are a little stiff but hold tune well.I’ve used these in my custom build.A few hairline scratches which can be seen when scrutinising but overall I’m happy with them. Amazon customer service are great for any issues.

I bought these tuners for a self-build bass project. They seem good quality for the price, and not too heavy. The pegs turn and hold tuning reasonably well. However, as stated in other reviews, the screws that are supplied are very flimsy and the heads will break off after more than 3 turns. I only tried one, and fortunately had some spares. If you buy these tuners, definitely worth getting some decent screws from a DIY store.

I wasnt expecting much, not at this price. But as I had a machine head on a second hand bass that felt like I was shovelling gravel when turned I thought I would bite the bullet and buy these to tide me over till I can get better quality ones. The bottom line is, I am not now looking for better ones having fitted the first of these. These are more than up to the jobWhat can I say, they tune smoothly, they seem pretty good quality and unlike another review I found the screws to be fit for purpose. My intention was to fit just one to fix the gravelly one, but I will replace the remaining three on my bass with the remaining three from this order. I am that impressed. I cannot risk having rubbish machine heads as my basses are gigged and work in studios regularly, so this gives a measure of how confident I am in the quality of these Musiclily machine heads

It sounds fine, but I cannot really say, as it did not fit my bass. It looks really similar to the ones I have on my bass, but it is millimetrically different. This ridiculously small difference made it impossible to put them in my bass. I tried all possible combinations of parts between these pegs and the one torn peg in my bass... I could not make it work. It is likely my fault, as I didn't pay attention to the model. Be sure this is the right fit to your bass before you buy.
