Price is for 2 knobs. These are control knobs for split shaft potentiometers in millimeter sizes, and are not set screw type. These are generic guitar control knobs. I was looking for something similar to the original knobs on my FERNANDES MG Mockingbird model, and I bought a lot of them, so I'm selling the extras. They look similar to the original FERNANDES knobs. They are about 1mm taller than the original 80s FMG knobs. Therefore, they are not exactly the same size, but as you can see in the photos, they look fine when installed on a guitar. I think these will be useful for those who use FERNANDES Mockingbird, HIDE models, etc., and have lost their knobs. (Up to 5 of the same product are shown in the photos. They are all the same. Three are installed on a guitar, and two are placed directly on the body.)
