Vintage relic processed bell knobs, as seen on Gibson Les Pauls. The patina has been recreated, referencing 50s originals and 59 parts. Recommended for those who feel that the knobs on their well-played guitars, such as Historic Collection or Murphy Lab models, look too new and don't match the guitar. Like pickups and bridges, changing these won't change the sound, but it will definitely boost your motivation. These are inch-spec. If you need millimeter-spec, please comment and I will make them. #Gibson #LesPaul #lespaul #Gibsonsg #firebird #flyingv #guitarparts #guitarrepair
