GotohLarge Schaller-Style Knob Tuning Machines, 3 Left & 3 Right, Gold

I have four acoustic guitars including a Furch Yellow Master’s Choice Gc-CR.The Furch has Gotoh 510 tuning machines which are absolutely incredible! It made me realize how relatively insufficient the tuners on my other guitars were!While these are not exactly the level of the 510s, being 16:1 instead of 21:1 ratio, they are really outstanding, smooth, and very high quality!I have since replaced all of the tuners on my other three acoustics with them. The only difference among them are different colors that suited each specific guitar.All of my guitars feel like they’ve been elevated to another level and it really is quite a different experience tuning my instruments. It is so much easier to dial them in now!Additionally, these are extremely easy to install, and only took a few minutes because they were a perfect fit. I just purchased the proper number one Phillips head screwdriver and a 10 mm socket wrench, considering I didn’t have to pay a luthier or guitar repairman, it was a very minimal additional cost!Highly recommended!!

It can be unsettling and frustrating to order tuning machines that should fit one's guitar without any drilling. I'm writing this review for anyone who wants to replace the mediocre tuners on their Ibanez Artcore hollow body guitar. These tuners fit perfectly, no drilling required. The screws on the back are a bit meatier (which is good), so you'll need to use a bit more torque when first installing them. The knobs on these tuners have a square-ish as opposed to the bean-shaped original tuners, and they seem to sit slightly closer to the headstock, but this doesn't interfere with access or operation.Lastly, these tuners are 14:1, which is plenty precise for me, and they are far superior to the stock tuners that came with the guitar.

Perfect, used on a Fender CJ290-SCE

These are a perfect fit for my Ovation Celebrity Elite. I was worried because nowhere on the internet did I find anything telling me what tuning machines would fit. These looked like they would and the specs matched as far as I could tell (I'm not a machinist) so I took a leap of faith.So far I have only replaced the factory Ovation machine that was broken, but it fit flawlessly, no modification needed, and is smoother than the factory machines. Brighter gold too and I like that. I'll be replacing the other 5 soon.

I got these for my G5222/5232. This is a perfect replacement. Much better quality and ratio. Direct replacement. No drilling.

Easily replaced the stock tuners on my IYV IJS 500 hollow body electric

These were a perfect fit for my cheap but good JPB acoustic! So easy to install & stay in tune!

I was surprised when I found these tuner knobs because I have been looking for them for quite awhile. They were a perfect fit.
