I inherited a '65 (or '64, can't remember) Gibson J-45 (I believe - will post photos tomorrow for you folks to confirm) acoustic from my mother a few years ago. I absolutely love it and it sounds wonderful. It is my main "around the house" guitar, but I would love to be able to use it out at acoustic gigs I do with my singer. The main issues I have with it is staying in tune, and the intonation. Individual strings can get in tune but when playing say, a G chord, a couple strings (usually G and B) are out of whack. On electrics first thing I usually do is swap out the nut for a Tusq or similar to help alleviate most of those issues but I am not eager to swap anything out on this as it has a lot of cool mojo. Any advice? Like I said I will try and snap some photos tomorrow.
