I do not know if this is where i should post this but i own a Gibson SG Standard and i need to adjust some things but everywhere i look on line and even when i messaged Gibson they all tell me i need to have a 64th of an inch ruler and use that to adjust it. For example Gibson says to make the low E string is 5/64 of an inch off the fret board when fretting the first fret and 15th fret for Truss Rod Adjustment........where is 5/64 of an inch?!?!? I have looked everywhere online and they do not exist from what i see. I tried converting it to MM but that does not help at all because it says some huge number like 3.9688 which i guess is almost 4mm? I am so confused and ready to just give up. I have adjusted many Guitars because most i have worked on go by mm and the manufacturer has the factory setup online but Gibson does not. I hope someone can help me on this.
