That supports my thought- that a "well-toned"
acoustic guitar will have produced tones. I can not imagine playing a guitar that had NO produced tones- it would be dull and boring. Well, I can imagine
playing one, just not
enjoying the experience... My afore mentioned 12-string- an Arbor, if it matters- is great fun to play, primary for it's produced tones. I can play just the octave g string, open, then finger-mute it and I hear the note continue to ring on. Muting the other strings, one at a time, locates it, vibrating in sympathy. I don't even
try to suss out the produced tones when I am playing more than one or two strings- just too much going on. I just bask in the warmth.
I am making a bigger point, here: that resonance you are trying to kill should be left alone. Now, this is my own opinion, and if you just gotta kill it, then kill it- but I think you might find you have "scorched the earth" quite a bit more than you wanted, when you are done. Maybe the best thing to do is to get another guitar.
