    Perfect Drop-in For Older PRS

    Posted by Dman on Aug 4, 2022

    These are great, perfect drop-in fit for a pre-lawsuit PRS single cut with traditional Kluson style tuners. Took longer to unwind the old strings than to actually install these guys!

    Quality Tuners

    Posted by JD on Jan 10, 2022

    I just installed them today, so I can't speak to how well they will work in the long run. I have a PRS Zach Myers. I had to remove the stock bushings as the tuners were too big to fit inside. Was a pain trying to get the new bushings flush due to the tight fit. .

    Gotoh SD90

    These were a drop-in replacement for my PRS McCarty. No issues with the installation and they hold their tuning. Very smooth feeling to them and very accurate.

    Really good tuners

    Posted by drbjstern@gmail.com on Jun 13, 2021

    I bought these tuners to replace Gotoh Vintage Non-Locking tuners as I was having tuning instability issues. They did indeed improve stability. They feel precise and extremely well-made. I'm really happy that I made the change.

    these work really well on my 2020 Epiphone SG's . . prefer using same hardware on guitar as to not mess the original screw holes up .

    GOTOH SD90 Magnum Lock Traditional 3x3 tuners Nickel

    Posted by Joe on Aug 12, 2020

    Philadelphia Luthier was very helpful, they answered my e-mail the next day on my particular Les Paul model. Received my tuners within 2 days and they fit perfectly. They stopped the out-of-tune problems w/the D& G strings & they look great, too! Very, very pleased w/Phil Luthier & the Gotohs!

    Works Well on my Gibson '59 Les Paul and '63 ES-335 Reissues

    Installed on my Gibson '59 Les Paul and '63 ES-335 reissues without modifications. Tuning stability improved, string changes easier, and looks discrete.

    Excellent Quality Tuners but Needed Ferrules

    Posted by Mr Mellow on Feb 24, 2016

    They work as intended. Only issue is that I had to also get AllParts headstock ferrules to get these to fit. Installing them was no problem once I watched a youtube video of a guy using a bolt, nut, washers and wooden block to slowly screw the ferrule into place. I was concerned about damaging the headstock installing the ferrules without using this method. Not a scratch on the guitar.

    From there, installing the actual tuners was a breeze - and they work great! Just be aware that MOST modern Les Pauls will require the ferrules because the opening is too large when the original tuners are removed. Custom Shop guitars are an exception, per my brother. Probably older models as well.
