Sorry, I know this is an old question/problem but have tried most common cures suggested, or that I can find. Sorry, long read, but it's something to do during this bloody lock down. I had a beautiful 1971 SG dot neck, perfectly balanced, action so very low. I sold it to my best freind a couple of years back who was in a 'name' band (No1's in UK and US amongst other parts of planet Earth) as I was too afraid to take it gigging as apart from, marks and dings etc. Last straw was having nearly driven away from the club we had just been gigging when I noticed it in it's hard case, in the street, leaning agaist the wall!! I was going to put it in last, 2nd guitar (Strat) already loaded. Thank the Guitar Gods for saving me and her (SG) by my noticing it at the last nano second. He records from home and with his lovely collection, very early 60's Strat, '61 Tele etc, amonst other beauties, he LOVES the SG most due to tones and Playability. I then aquired a new, at the time ( 1990's ) Epi SG, it looks great,action good, but I can't play it as it neck dives like an Olympic Diving champion. I trimed about 1/2" off the end of the head stock, moved neck end strap button and then the main body button. Result? Zilch, maybe slight from about 45 degrees to 30, but I can't play AND support weight of the instrument. I don't really want to add weight unless that's last thing to try, car wheel balancing lead weights in electrics cavity, something like that. Anyone got any better ideas ? I would really 'ppreciate a solution so it is more than a wall decoration.
