This will create a very small amount of additional pressure on the bridge. The alternative is to reduce all the offsets by 0.61 cents, meaning that A4 would be tuned to 439.8 but the overall pressure on the bridge will be unchanged. The difference is negligible so I would not worry about it.</FONT></STRONG></DIV> <DIV><STRONG><FONT color=#008080 size=2></FONT></STRONG> </DIV> <DIV><STRONG><FONT color=#008080 size=2>The note you are moving furthest from ET is D#, almost 7 cents sharp.
