Beautiful upgrade for my old guitar

These knobs look absolutely stunning on my acoustic guitar. The pearl finish catches the light perfectly, and the concave shape makes tuning much easier than the old flat plastic ones.

Easy installation

Took me less than five minutes to swap all four knobs on my electric guitar. No tools needed other than a small screwdriver to remove the old ones. Looks great.

Great fit, slight color variation

They fit my machine heads perfectly without any modification. The white is slightly more cream-colored than pure white in the photos, but it still looks very classy.

Excellent value

For the price, you really can't beat these. They transformed the look of my budget guitar into something that looks much more expensive. Highly recommend.

Perfect for ukuleles too!

I bought these for my soprano ukulele and they work like a charm. They add a nice touch of elegance and the grip is excellent for quick tuning adjustments during practice.

Solid construction

Very impressed with the build quality. They feel solid and not cheap like some other replacements I've tried. The red agate color is deep and rich.

A: Yes, these knobs are designed to fit most standard machine head posts found on Gibson, Fender, and generic brand guitars and ukuleles.

A: No glue is required. These caps simply screw onto the existing post of your tuner mechanism after you remove the original knob.

Q: Can these be used on bass guitar tuners?

A: They may fit if your bass guitar uses standard-sized tuner posts similar to electric guitars, but please check your post diameter before purchasing as bass posts can vary.

Q: Are these sold as a set of 4 or individually?

A: The package includes a set of 4 knobs, which is enough to replace all tuners on a standard guitar or ukulele.

Q: Is the material real agate stone?

A: The knobs are made from high-quality resin composite designed to mimic the appearance of agate pearl, ensuring durability and consistent coloring.
