Hi all, new (to me) guitar and need to buy a volume pot. Want to replace with the same or similar, so what did it come with? I'm guessing long shaft and 500k but did it come with audio or linear as standard? Pics from listings below - CTS & 'Gibson" pots. Gibson has a lip washer at the top of the shaft (arrow) which is absent (arrow) on the CTS. Mine has the washer. Also Gibson has some tabs which I think are to hook onto the pot assembly base plate. Other pics of pot mentioned (arrow) and knob. Any advice or experience welcomed Thanks.
