If you want a knob with a picture of a skull on it, this is for you!
But seriously, it is a high quality knob, which can be tightened with an allen bolt onto your pot. It is well made, but does not fit a solid-shaft CTS style pot, only a split shaft one. So it's worth knowing that, before you buy. It is also physically smaller than a classic telecaster knob.
The burnished look is quite cool. The graphic is tasteful (if you like that sort of thing). People do notice it. I think it's a cool product.... but not for everyone!!
