I bought these for my Schecter Omen Extreme to match my ruthenium bridge and tuners and these are perfect.
I needed 2 knobs and ordered 2 packages by mistake and now I have 4 (two spare) :) but this is OK since I can keep these for my future guitar.
The knobs are heavy and the grip is very good. The internal surface (for the pot shaft) is smooth without grooves.
My only grief is that the screw is on the same side as the position dot and since I like the dot to point towards me when full, I also see the screw. Not a big deal but some people might not like this.
The delivery from Thomann was flawless, so thank you very much!
