I had a really horrible experience with my J Custom, the guitar looked great, sounded pretty damn good after I changed the pick ups out too, I wasn't wild about the dimarzio IBZ's.. but heres where the saga begins... ok a little dramatic but my personal experience lol.
I bought it SLIGHTLY used, basically someone bought and returned it so I got it for a little discount, it was brand new tags and all not a pick swirl on the damn thing. It was a RGT320Q by the way..
After I think like two weeks, the 5 way switch went bad, and its a printed circuit board switch and it has this little ass ball bearing inside of it, and once part of the metal wears a little bit, the ball can come out and the thing is totally useless, so I had that replaced, never could get the wiring proper with out the PCB switch though, ended up with a PRS config which I never liked as much as the original switching. Then I switched out the pick ups because the stock ones were a bit thin and just didn't sound all that hot, put in a Air Norton and a Super Distortion, loved the Norton, wasn't wild on the Super.
Then after I got the switch fixed, put in new pick ups, literally like two days later the volume pot froze, just completely stopped turning... back to the repair shop again.
Got it back and it worked yaya... but I always had issues with the bushings on the tremolo arm, I use 10-52's so the damn things would CONSTANTLY wear out, so I tried to fill it with teflon tape, or you can heat them up to swell them with a lighter but the arm always gets loose, so I got a screw in kit and replaced that part of the trem, it helped but still would get loose and back out.
The guitar was nice, well made physically not electronically, and the edge trem arm just sucked imo, I've got PRS trems and Suhr trems non locking that the arm is WAY more stable on either.
Eventually I broke a string while using the trem arm and went that day and got rid of it. I don't think I'd ever purchase another one just because the electronics were made so shitty, and I'm not like one of those people who beats their guitars, I've had many guitars with no electronics issues at all.
So theres my vote, I'd say no, but maybe if its an older one better parts who knows?
