Fast service and the tuners work great

I bought these tuners because I was having tuning stability issues with my Les Paul Custom. The guitar already had standard Grover Rotomatics (the non-locking kind), but just wasn't staying in tune. I couldn't really make it through a whole song end to end without the guitar going out of tune and wasn't sure whether it was the nut, tuners, or something else. I eventually decided to try things 1 by 1 until the problem was fixed and started with the tuners.

I'm not a guitar tech nor am I particularly handy at fixing stuff and so I specifically bought these tuners because are were a direct drop-in replacement for the original rotomatics tha came with the guitar. Since it was already fitted for Grovers, they were easy to install with no drilling required. All told, it probably took me about an hour to swap out the tuners and restring. I also widened the tuner side slot openings on the nut for the G & D strings. It's only been a few days, but tuning stability appears to be much improved and I'm quite happy with my purchase.

Drop in replacement for cheap probably Gotohs on a 90's AS80 Ibanez project. Not as good as comparable Schallers but that's another $40+. They get the job done.

Replaced my original Epi LP Custom Pro gold Grover tuners with these black Grover locking tuners. Love them. Really like the look on the guitar and ease of changing strings. These replacements fit perfectly and no issues. Highly recommend.

These are great tuners, perfect for any guitar with stock Grovers. Upgrade in tuning stability and countless hours saved changing strings. My favorite from Grover, and the best price is right here.

I ordered these for my les paul, and another set for my V. Easy to install, Easy to change strings, hold tuning well. Best tuners, and best price from amplified parts. Gold looks great on cherrybursts
