A little off topic but I have a 1987 Jackson Dinky that sounded absolutely amazing but noticed it was lacking the greatness I once remembered... just lack luster in general, I actually thought it was my ears or even my memory was skewed... the original 500k was working properly "ohm reading ok, no scratches or dead spots"... I took a chance and replaced it with a new Seymour Duncan 500k pot and MAN what a HUGH difference it made!... it literally was like someone removing a blanket covering the speaker cab... "SMOOOOTH as well"...
I am now a HUGH Seymour Duncan potentiometer fan👍🏼
Also Pure Tone Jack's as well
