It seems that theres a slight issue with the 6th string on my strat. When I hit the 12th fret it rings high. Ive tried turning the screw anticlockwise until its really loose-surely it should never come loose because of the spring?
So I tried turning it clockwise and retuning the string, still sounds sharp.http://soundcloud.com/cameraman59/intonation-issue
Could it be a string action issue? The rest of the strings are fine.
