    Hey everyone, this is my first post here. However, I've been spying on this forum for several years now; I figured it was time to officially join the collective of this awesome and rare guitar.

    I purchased mine 15 years ago for $350. It was (and still is) glorious, until someone backed into on stage and the headstock nearly snapped off the second it hit the ground. After it sat for the last 8 years, I think its about time to start refurbishing it into the true beauty it is. I still have almost all the original parts, accessories, and electronics. It's just extremely beat up.

    I'm debating what color/stain to paint, and methods for achieving a near factory finish. Anyways, I'm glad I finally joined.

    YES!!! I figured out the problem with my circuit board!!!

    I do amp repair and I build stomp boxes and I have all the tools but i had been puzzled why my RD SG circuit board would not pass signal through the first transistor I checked voltage on the source drain and gate and it seemed too low on the source lead 1vdc i knew it needed to be like 2.5 or 3 volts to turn on the fet I finally figured it out and it is passing signal to the output jack!!!!:dude: there was a lttle piece of the lead barely touching another pad shorting it down to 1volt. I traded a Dean hollywood Z for this SG in a broken state back in the mid eighties not having much electronics know how back then I just wired straight up gibson style controls.now 30 years later it rides again!!!:applause: Im so happy I could **** LOL will be loading the electronics back in tonight Im on lunch break.

    Almost finished

    [​IMG][​IMG]Ok I included some pictures of my improvised plugs you might not want to use shrink tube as long as i did im probably going to cut it back when i take the board out. To the fellow i told use a 250k pot for a tone replacement DONT!!:ohno: I found out this works much different than a regular tone knob get a 100k and nothing else just make it work I was trying to get one that fit the board perfectly but the higher value takes away volume from that pickup. The board first sounded crackly:dunno: I cleaned up the switches and jack with a small jewelers file.Normally i use contact cleaner but these contacts were some of the worst Ive seen in a while. After doing that i have a beautiful clean tone with a wide variety of frequency shaping.I do have a low output from the neck pick up that is directly related to the higher value tone pot. Overall Im happy never thought id see this board work a little more tweaking and it will be ready for action.

    Add another working one to the list!

    I was wrong the 250 k pot works great it was a coupling capacitor that was not connected to the pot.It is a monster now I love it. I also put a battery holder in mine.

    For any one wondering how those pickup pins work on the board the two outside pins are ground the middle is hot if it is a 4 wire pickup jumper two wires to make it a humbucker and take the remaining two black should be hot green and the shielding wire go to either side.

    Your connectors are very clean, I like it a lot! It's amazing how far electronics/wiring have developed since this guitar was made. I look forward to completely rewiring/resoldering nearly everything once I have all the parts ready. I'm experiencing a good amount of crackling when I turn up the volume all the way, and turn on the on board treble boost switch.

    Looks great though! Thanks for the pics.
