hey everyone, im a guitarist who tries to take care of his own guitars. i have this epiphone sg custom ive been playing for almost a year now. ive recently put 8-38 on it and top wrapped the strings. the action is VERY low and it plays like butter. theres no buzz apart from the d string 14th fret, it touches the 15th and dies out very quickly. could this be a high fret? there are no other buzzing anywhere and the neck is almost straight.

also the g string 7th / d string 12th frets die out instantly, and the open d string sounds week, like some freqencies die out. would heavier tuners or anything else fix this? im ok with it shifting to a c# or d#.

thanks everyone in advance. im pretty new to these things.
