Fender Standard/Highway One Series Machines-Set of Four Bass Guitar Tuning Keys (0036400049)

The tuning machines on my 1992 Fender (Mexican) Jazz Bass were slipping. I tried using glue but that didn’t work. I got these replacements last night and they were perfect! I did not have to drill any new holes and I used the existing bushings even though these came with two sets of replacement bushings (two sizes). My 1st photo shows a new machine on the left of the headstock and existing on the right. The new ones look nearly identical except for the missing “Licensed by Schaller” stamp. One big improvement is how these are keyed. They have a more square shape (2nd photo) versus the octagonal key (3rd photo) in my original tuners which wore out and caused the slipping problem in the first place. I’m very happy with these!

There have been other comments about the bushings being too small, but my Highway One tuners included two set of bushings - one slightly larger than the other. I ended up installing the larger diameter bushings by using a small reaming tool on the holes in my MIM fretless replacement neck to get a perfect fit. Installed, they seem very solid. The gear ratio works well, and allows for granular-enough adjustment in tuning. After a small application of grease, these are also incredibly smooth. Aesthetics aside, there is no difference in quality to the covered Fender USA tuners on my other basses. If this tuner set had only included the smaller set of bushings, I would have been disappointed. However, Fender appears to have heard the complaints and responded appropriately.

These fit my Squier 40th anniversary P-bass perfect. No drilling needed. I even called Fender and asked what would fit that bass and they didn’t know, so I am glad I gave these a try.

Great tuners except they came missing 1 of the 4 bushings I needed for my bass. This set comes with 2 sizes of bushings and it had all 4 of the smaller set in the bag. Was refunded roughly $12 which is almost enough to cover buying the bushings outright. Could of replaced the tuners but it would take way longer than just paying for the set of bushings and losing about $1 on the deal.

These are excellent replacement tuners - much better than some of the cheaper reproductions. The gearing is accurate and tight and the mounting holes line up exactly with those of the original worn-out tuners so swapping them was quick and easy.
