I recently got my new guitar (yeah long overdue NGD I know) but here's the thing. It has this problem. Worked fine for about a week, then when I now try to switch pickups from bridge to neck, the bridge pickup sounds good, but the instant I switch to neck it sounds thin , weak and powerless. I pull the cable out of the guitar and put it back in, adjusting it a little bit and it sounds good again. Now when I go from neck to bridge, the bridge sounds like shit. I have to adjust the jack again. It's running EMG 707s in your standard 3 way. Battery checked, it's not a battery problem.

Any suggestions? What do you think is wrong?

Thanks folks!
