I really like the look of this knob, it is well made, the numbers are very easily readable (they are magnified by the transparent plastic which gives you that wristwatch effect) even when the light is dim and it just feels solid.
Unfortunately, the knob is intended to be used only with the arched top guitars (Les Pauls) and when you try to put it on a non-arched body, it probablly won't fit very well as it is rather shallow and will be sticking out a bit. Also keep in mind that it is pretty wide (6 mm) and you may have less space to turn your pots, if they are close together. Personally, I would like to see the same looking knob, that would have the T-style format.
The price is adequate, it is solid quality and the original knobs tend to be a lot pricier than this.
