You basically did the IT version of turning it on and off again.
Glad it got solved.
PS - when you put it back together, was it the same strings or a new batch?
I'm very intrigued by Eagle's comment about counterfeit strings; especially as a player who rarely changes them until they break, or my harmonics stop sounding out. (about 6-7 months based on playing time currently. Used to be 1-2 month based on playing time)
