The guitar frequency response
Graham Caldersmith · The Journal of the Acoustical Society of America · 1982
The guitar frequency response is found to be a good predictor of two important parameters of guitar tone: initial level of the partials and initial level decay of the partials. A high initial level normally gives a rapid initial level decay, but under some conditions the higher level may more than compensate for the initial level decay and thus give a tone a longer duration. The condition of the strings was found to be much less significant than the frequency response of the guitar body.
