Premium Slot Top Synth Control Knob
Premium Slot Top Synth Control Knob
This distinctive control knob features a robust construction with pronounced ridges around its circumference for enhanced grip and control. The knob's most notable characteristic is its unique position indicator system, comprising a recessed slot that runs across the top surface and continues down one side, creating a clear visual reference for precise positioning.
The flat top surface incorporates a white square indicator positioned within the recessed slot, providing excellent visibility against the knob's surface. The ridged sides offer superior tactile feedback and secure finger placement, making it ideal for applications requiring precise adjustments in professional audio equipment, synthesisers, and high-end electronic instruments where both functionality and visual appeal are paramount.

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.
