I'm not exactly sure how to explain this but when I hit the low C or the C one octave higher something in my guitar is resonating. It's strange that it is only resonating at that frequency so its not like something is loose and just vibrating when any random string is hit. Something in the guitar is actually being excited by the frequency of the C note and its octave. Is it possible for the tremelo springs to resonate cause it sounds like a very metallic resonance? Its not like its being picked up electrically but acoustically I can hear it and its enough to bother me at times. Any thoughts?
*edit* it's a schaller trem btw
