Solid Colour Domed Top Guitar Knob

Solid Colour Domed Top Guitar Knob

This control knob features a smooth domed top that rises elegantly from a cylindrical body with finely knurled circumference. The knurling provides excellent grip and tactile feedback, whilst the clean domed cap offers a sophisticated appearance without any position markings.

The knob's compact dimensions and substantial feel make it particularly well-suited for guitar volume and tone controls, audio mixing equipment, and electronic instruments where both functionality and aesthetics matter. The grub screw fixing ensures secure attachment to round shafts, making it ideal for applications requiring reliable, wobble-free operation.

Hole Type

Round Hole

A knob designed for a round shaft has a smooth, cylindrical hole that matches the shaft's shape. This type of hole allows the knob to slide easily onto the shaft, relying on a grub screw / set screw or friction to keep it in place. This design is widely used in audio equipment, consumer electronics, and control panels due to its simplicity and versatility

A knob with a round hole can typically also be used on a D type shaft in the 180° position (where the position indicator is opposite to the flat of the D) and can often also be mouned to splined shafts in low torque applications.
