Ok, I'm going to ask for a little help from the experts if that's ok:
So, here's my first problem. I am finishing my first full build, and no matter what I try, the strings are still making a nasty twangy sound whenever I play them. I've tried to adjust everything, and nothing has changed. I'm about ready to just give up , and would rather not considering the time I put into this. If it helps, I can add pictures, but its specs are pretty simple; 25.5" scale with a stop tailpiece/tune o matic bridge and a standard nut, angled headstock.
Now the other problem, which may be related to the other one. I really don't know. After adjusting the truss rod as far as I can, and (again) anything else I can think of, the action is uneven. Near the first few frets it's great, really low but not too low, but the farther down the neck the higher it is.
Any help would be appreciated, I'm just getting pretty frustrated. If pictures would help, I'll add them. Whatever it takes...
