These will happily replace any damaged or missing control knobs on your Gibson style guitar. Given their own particular style, you should look to replace all the control knobs with these at the same time as just one will look out of place.
Not much to say here really. Good quality, solidly built knob, when mounted on a guitar it is sturdy and feels good to rotate.
I got a pair of these, volume and tone, to replace the standard knobs on my Telecaster. I wanted 72 deluxe Telecaster style knobs - these were the closest match I could find. They look great mounted on my guitar and I'm sure they would easily also suit other types and styles of guitar.
Attaching them onto the rotary pots on my guitar was simple and easy - just push them down firmly until they fit. No screws involved and they are firmly in place.
