【Brand New】 Set of 4 vintage-style wood knobs. Material: Rosewood Inner Diameter: 6mm ※Please note that the wood grain and color may vary from piece to piece and may differ from the photos. 【Product Description】 A calm presence, like a musical instrument that has aged over many years. These vintage-style guitar control knobs utilize the natural texture of wood. They offer a soft, deep texture that cannot be achieved with metal or plastic. They make a subtle yet definite statement, giving your guitar a classic, refined look. The shape fits naturally in your fingertips, and the smooth turning action allows for stress-free use on stage or at home. They are also a perfect match for relic finishes, sunburst finishes, and semi-acoustic/full-acoustic guitars. The individual differences in wood grain, which are not found in mass-produced items, will make your guitar "one of a kind." Features: Made of natural wood (wood grain and color vary from piece to piece)
