I tend to agree that if an instrument is properly set up then the amount of pressure applied to the string or how close you get your finger to the fret should not make the kind of difference that people complained about. If the resulting note goes sharp if you press harder then there is something wrong with the instrument. Same if it buzzes. A suggestion to place your fingers differently or to press lighter is a poor workaround at best not a fix for the problem.

As I said I have the problem of notes going sharp on one of my guitars not on the others or on other guitars I have played. If the problem was my technique it would follow me from instrument to instrument. I currently believe that the problem with that one instrument is due to frets that are too high. I still have not had time to take it to a luthier.
