What to know before buying
Listing details to confirm
The listing is inconsistent about the control arrangement: its title says 1V2T, while one feature line says 2T1V. Both describe one volume and two tone knobs, but confirm the layout and that the listed 6 mm inner opening fits your pot shafts before buying. The listing also says no mounting screws are included.
Who is it for?
A good fit for
- Guitarists or bassists replacing three control knobs on an instrument whose potentiometer shafts match the stated 6 mm opening.
- Luthiers or DIY users wanting top-hat knobs with numbered position markings.
Less suited to
- Buyers who need a confirmed fit for a shaft diameter other than the listed 6 mm.
- Anyone looking for metal knobs or mounting screws in the package.

Aggregate ratings lean positive, with most ratings in the five-star category, but a smaller one-star share means the overall picture is not uniformly positive. The ratings do not explain the reasons behind either reaction. For buyers, the key practical fit question remains the listed 6 mm shaft opening, which ratings cannot confirm for an individual instrument.
