The quality of manufacture leaves nothing to be desired visually. The gold is very gold and shiny and the abalone tops are stunning.
However, I have an issue with them that was a deal breaker.
They are constructed such that they tend to sit very high off the surface of the guitar, because the skirt around the base is simply not high enough to allow the nut and washer of the pot to be hidden up inside the base of the knob. This is even worse if you use push/push or push/pull potentiometers, with an air gap of 4-5mm BEFORE being pushed or pulled into their UP position.
