Okay, I know my topic doesn't make sense, but hear me out...
When I open tune my guitar things seem good, and if I do harmonics at the twelfth fret things seem well intonated (is that a word?). However, when I play octaves or chords up the neck I can hear that my B string is clearly out of tune in relation to my other strings and I have to tune it down about 15 cents in order to get rid of those horrid "waves" you hear when a string it out.
Any idea what could be causing this? Or, more importantly, how to fix it? I don't think it is a bridge position issue because my E string is fine, although there is a slight "hitch" in the way my bridge is designed.
Thanks for any advice.
