so i have an ibanez sdgr sr800le. i got it used a while back at a guitar center. i recently wanted a new amp so i tried selling it to guitar center. they looked at it and said probably $25. then they plugged it in and it played one note then died. we changed the battery, the cable, the amp and it still wasnt working. then the guy said "your electronics are dead. ill give you $10 for it." i was mad about only getting 25 for it. so i left with my bass. but now i wanna fix it because i wanted to customize it and get new pickups and defret it. any advice on what to do about the whole "dead electronics problems?
