I don't know if "intonation" is the right word in English, but my guitar (Dell' Arte model Angelo Debarre) is really out of tune at the 12 fret. This happened right after i changed strings (Argentine loop end 0.10). When i have old strings on my guitar the intonation is quite off, but it usually fixes itself when i change strings.
The last time i changed strings it just got worse. I have of course tried moving the bridge but i can't move it enough to fix the problem. Does anyone have any tips that might help dealing with this problem?
I live in Norway and the temperature out side was quite extreme this winter, but my guitar survived it. I use an air humidifier i my case.
Thanks for answers. Oliver.
