MECCANIXITY Aluminum Potentiometer Knobs, 1/4-Inch, 2-Pack, Silver
Product description
Some instrument updates call for a full setup change, others only need a fresh control knob. This two-piece MECCANIXITY set is made for replacing or refreshing compatible potentiometer knobs on guitars, basses, amplifiers, and other music equipment.
Want a focused control refresh that keeps the existing potentiometer in place? The screw-type knobs fit a 1/4-inch (6mm) mounting hole, and the included wrench helps secure them during installation.

Each knob combines an aluminum alloy body with an anodized finish and a rubber ring. The silver finish and bright red rings add a distinct look while the rings cover the fixing-screw holes.


Product specs

The knobs measure 40 x 18 mm (1.57 x 0.71 inch) in outside diameter and height. Their mounting hole is 1/4 inch (6mm), so the key selection step is matching that opening to the potentiometer shaft on your instrument or equipment. Measuring the shaft diameter before installation helps establish whether the fit is right.
- Type: Screw-type potentiometer knob
- Material: Aluminum alloy with anodized surface, rubber ring
- Color: Silver knobs with bright red rubber rings
- Dimensions: 40 x 18 mm / 1.57 x 0.71 inch (outside diameter x height)
- Mounting hole: 1/4 inch / 6mm



The aluminum construction gives the control a solid metal body, while the ring finishes the area around the fixing screw. Compared with replacing or modifying a larger part of an instrument, these knobs offer a direct way to update the control you handle when adjusting volume or tone.
Everyday use

Use the knobs as volume or tone controls on a guitar or bass, or as adjustment knobs on compatible amplifiers and other musical equipment. They are suited to a practical replacement when an existing knob needs an update, as well as to a coordinated refresh of two controls. Their 40 mm outside diameter provides a broad knob profile for routine adjustments, and the rubber ring is designed to cover the fixing-screw hole.


Installation starts with removing the old knob and measuring the potentiometer shaft to check its diameter against the 6mm mounting hole. Align the new knob with the shaft, secure it with the included wrench, then place the rubber ring around the outside. Matching the shaft size before fitting is especially useful when replacing a knob across different instruments, since the mounting fit is what determines whether the part is suitable.

What you get
The set includes two silver aluminum potentiometer knobs, two rubber rings, and one wrench. That gives you the hardware for two matching control positions and the tool for tightening the screw-type fittings. The red rings add a contrasting detail to the silver finish and cover the fixing-screw openings once in place.

Should you buy it?
Choose this set for a straightforward control refresh on a guitar, bass, amplifier, or other music device with a compatible 1/4-inch (6mm) potentiometer shaft. It brings together two matching aluminum knobs, red screw-covering rings, and an installation wrench, making it a practical fit when you want to replace a pair of controls without turning the job into a broader equipment change.
