Lot of people complain about the cheap selectors and wiring used. It’s a simple fix and quick replacement…but getting unreasonable for a now $1.7k guitar that this is an issue. I wish they would upgrade the switch selector and wiring to that of core. Keep the cheaper wood top and pickups to keep the cost down.
I had to do the same thing after I got the guitar back from having the 58/15 LT pickups swapped in.
I had a similar issue with my S2 594 when I first got it. It would be really inconsistent when switching between pickups. A little electronics contact cleaner took care of it no problem.
