Thanks for the tip, guys.
Just 2 cents on loosening strings subject... Remember that truss rod is constantly bending the neck away from strings and for this reason its adjustment is made to balance strings force in oposite direction. So, if you loose strings and doesn't touch truss rod you'll have the neck flexing in just one direction (curving the neck, bringing strings closer to frets, making it more prone to hit them and probably changing entonation settings). It is a good bet hope everything will be back at exactly place they where before, specially with old strings, but the fact is that the neck is being bended back and forward each time you loose and stretch them again. Considering we're talking about woods, results can be effectively unpredictable, don't?
