Wooden knobs. Sold as a set of 4. Can be used as pot knobs for guitars, basses, and other instruments with knobs. They are attached to the pot with a hex wrench, so they can be used regardless of the pot's size, whether it's metric or inch. They would look great paired with instruments with ebony fingerboards, or by matching the color to a wood-grain guitar/bass. Surprisingly, they also go well with modern guitar designs like Strandberg and Aristides. By attaching them to a modern instrument, you can add a touch of natural texture. I think it's rare to find a set of 4 at this price, so please take this opportunity. Although they are new and unused, they are handmade, so there may be individual differences and minor scratches from the manufacturing process. Please refrain from purchasing if you are sensitive to this. Shaft diameter: 6 mm Pot diameter: 20mm Pot height: 17mm #GuitarParts #WoodenGuitarParts #WoodKnob #WoodenKnob
