Shortly after my recent 1977 Ibanez SG copy NGD I stumbled on this listed on my local GC's used page. Was originally listed at $1100 (on the lower side of the usual $1500 I've seen on Reverb) but then marked down to $899 because the electronics did not work. I pointed out that I was taking on a lot of risk in buying this and that they are stuck with a "turkey" waiting for just the right buyer... I was that buyer and would take it for $700. Deal! Got it home... battery contacts looked corroded so I cleaned them but still no go. But it looked like I was getting voltage on the power cable *inside* the guitar (after taking off the access cover on the back) so I figured it must be a problem in the pre-amp. So I pulled preamp box out and then removed the circuit board from that. Got the schematic online and tested it on my bench with power supplied directly to the board. All seemed fine. Hmmmmm... So I went back to looking at the battery compartment and discovered that the spring contact inside it was bent and was not making good contact with the battery. Gravity made it contact when I initially turned the guitar over to check if I was getting power inside the guitar - which was the red herring that made me pull out the electronics! So I bent the spring contact back into shape and tested that I now reliably got power to the inside of the guitar. Then I put the whole thing back together - cursing all the way! Voila! Good as new for less than half the price of what they typically go for. Also used hot glue gun to fix a tattered portion of the case lining!
