All guitars have a resonance, and pst the software theory is the actual practical carving (I have got my hands on some sound analysis tech that measures "real" resonance from objects), so I would do some whittling after the carving.
And if you have a freqcency that interferes with that of the string vibration, then you're in trouble because you get muting and odd harmonics. While it doesn't really matter much, I quite like the challenge of getting a "perfect" sound, I am just wondering if the guitar should resonate at the root note of the normal tuning I use.
But thanks for all the help
