About 15 years ago I had the harebrained idea of fitting vintage parts to a les Paul standard, hadn’t really picked up on the whole historic thing at that time. So not really knowing what the hell I was doing I ordered 4 cts pots from an eBay seller in the ‘states, listed as removed from a 335 1960 or some such. Cannot remember what tbh. Any ways I have just found them and measured them. Two are 550k and two are 450k. So will probably get round to fitting them to something, will compare to pots on my R9. What I also bought was a pair of supposed bumblebees, although armed with new knowledge I see there is no solder bulb At either end, but I am curious as to what rating they actually are. But how do I measure them?
