Guyker 3x3 Vintage Style Locking Guitar Machine Heads – 1:15 Ratio Lock String Deluxe Tuning Key Pegs Tuners Set Replacement for Electric, Acoustic or Folk Guitars - nickel

I've always used Grover 502 Series locking tuners on my Gibson Les Pauls. But my most recent Les Paul Custom P90 (a 2024 Epiphone) has Kluson style tuners. I wasn't about to fork over big bucks on a guitar i wasnt sure I'd keep, so I took a gamble on these. They were 100% drop-ins and I used the existing bushings and screws. No problems with stringing or tuning. I'm 100% satisfied. My only concern would be longevity if I should keep the guitar.

These tuners look great and work great and were a direct fit. I'll definitely be looking into more products from guyker you can't beat the price.

I purchased the white which is actually a cream. They did match the existing tuners that I replaced on the PRS SE McCarthy. The holes are smaller than the existing tuners so I enlarged the holes to accommodate the larger screw other wise I would have needed to fill in existing holes on the guitar. Looks and works great. No tuning issues.

Great tuning machines , Nice finish , Accurate ratio, Went on without a hitch. Installed on a Chibson SG guitar. Excellent upgrade. Quality product.

Take a chance on these lesser expensive Guyker locking tuners. Took all of 10-15 min to remove old tuners and drop these in. Screw holes lined up and perfectly. They’ve been in use for several months. Great quality for the price.They seem to hold tuning as well as any others I’ve had, and makes string changing much faster.I leave very few reviews but felt this one was worth sharing.

Leave in the stock bushings. Use the stock screws. The holes that mount the tuners to the head stock have to be drilled to 7/64! Not the Guitar JUST THE TUNERS. Takes about 3 minutes to drill the 12 holes.Smooth feel, work very well, holds tuning, and gets rid of those dang gray knobs.

long of the short, these all had burs on the string port which kept causing high e snaps just at the port. I use EB RPS strings and the fact that Ive gone through high E's in a month is an issue. And before you think its from over tightening the lock, wrong. this last set i ran like a standard tuner and took the lock out. I detuned the guitar once to take the pickup out and upon retuning... SNAP. Graph techs are are on order. These will go in the trash. Save your money. Im not out $20 in strings and hours of frustration.

I bought these to replace the stock Kluson machine heads on my Gibson SG Standard. I was looking for something that retained the look of the Klusons but offered the tuning stability of a locking system. The tuners themselves seem solidly built with the usual thumbwheel to pinch the string in place. Your mileage may vary with your instrument but here are how things lined up for mine.1. The bushing was a bit smaller than the stock. This made it difficult to center the post in the opening. I did my best.2. While centered (as best possible) the existing screw holes do not quite align with the new machines.3. The bushing system doesn't have a screw type mechanism that the stock tuners do. The screw type (where the bushing screws into the post) provides a clamping action on the headstock which adds stability. The only thing these have keeping them in place are the two screws.4. Because of the slight offset due to the bushing size the string tension pulls the machine a bit so it's not level like it should be.In the end I removed these and put my stock tuners back on. I messed with the stock bushings and they helped a bit but the lack of a "clamping" mechanism left me a bit worried about overall tuning and structural stability.If these fit your instrument I think they will be a good option. I took a chance and thought the measurements were close enough. Not in my case.Giving three stars as they didn't work for my application but that isn't necessarily the fault of the item itself.
