If that guitar is a solid. Clean and original as it appears, my advice would be to leave the electronics original. It should have 1meg pots, which I don’t particularly care for. I would never change them if they are original, though. Non-original solder joints will affect the value of the guitar. I would sell it before I would change it. YMMV. Nice collectible acquisition...IF it is all original. My thoughts on these ‘collectible’ Fender guitars is that if one doesn’t like what they do, it is very easy and less expensive to buy or build a guitar that does what one likes. I personally do not pay big bucks for a guitar that doesn’t do what I want and then change the guitar...and start losing money in the deal. Again...others’mmv.
