Hi There~ I got a new hollow body guitar and silly old me took off all the strings at once and realised the floating bridge. I put it all back together and tried my best to measure the distance between the nut + 12th fret : and the 12th fret + bridge. i also adjusted the saddles as i put a different gauge on and i got the 12th fret harmonics equalling th 12th fret. Although it sounds fine on the 12th fret -its terrible in other places especially on the first 5 frets. How do fix this??? Im stuck... and what should be the first steps taken in the future.
