Assuming you have the same amount of (high) gain, and the same amount of distortion, a palm muted strum gives a higher output than when you hit the same chord with the same amount of energy, non muted. Why is that?
Suppressing the amplitude of vibrations of the strings should adversely affect the amplitude of the output signal but that doesn't appear to be the case. I am assuming this has something to do with reduced harmonic vibrations that might cause destructive interference but I'm not sure about the physics. Could someone explain the physics of this?
By higher output I mean the power or loudness of the signal. Here's the simplest demonstration.
