It’s a good point Tim (although, given recent posts, I might’ve deleted it without looking 🙂 ).

Korean instruments use locally-sourced electrics and, especially for 90s instruments like the Aria, they can be a bit not-great. I have ridded some of their useless jack-socket which would DURDUR incessantly, but not bothered with the tone knob (principally because I rarely use it).

If replacing the pups, it is well worth spending a few extra pounds and minutes following through with the rest. CTS pots and a Switchcraft jack are more substantial. OTOH, many pup people supply the rest of the kit anyway (EMG being an example). There comes a point when the switch cleaner is fighting a losing battle and that grit being swiped around is ruining the contacts. BTW, the rule is to use the type with no residue on sockets and suchlike, but make sure you use the type leaving a lubricant for pots.
