    Got these for quicker on-stage string changes in a 52 RI telecaster and they're perfect. Dropped right into the existing bushings. Took 5 minutes to swap them in and they look exactly like the original vintage style tuners. Well made, nice ratio. Get em!

    Installed easy, works great

    No issues on installing them on my Fender Custom Shop '63 vintage guitar. They look good, work great, and are much easier to string and tune.

    Just what the Dr. ordered ! Hard to find product. Easy to install, even by a rookie with no skills . Need only a small phillips screwdriver, and heavy set of pliers. No drilling. Perfect fit on a Fender Classic Player Jaguar HH . Stock ewquipped with "Kluson" looking (probably knock off) 6-inline tuners.

    These are excellent. I put them on a vintage style partscaster that I wanted to retain a vintage look to the guitar. They look the part and work beautifully. No slipping or sticking. I've got another partscaster and I'll be ordering another set.

    Very well designed and functioning; well worth the modest expense. Shipment was very fast. I will definitely use similar products by GOTOH and use Philadelphia Luthier Tools and Supplies in the future.

    Good quality.

    Posted by Max on Jun 29, 2018

    Very good replacement of standard tuners on my Fender Squier Classic Vibe 50s. External diameter of Gotoh bushings were slightly bigger than standard (~0.1mm). In my case it was enough using clamp to press them inside.
