I'm not a guitar player but have dittled with some at the music store. I can Feel the difference just holding and moving my hand upon one guitar from another. Watching guitarist friends trying out different guitars. Sound is first off. Listening while strumming chords. Tune it up. But once past that they seem to be more interested in moving upon it to make music. Kind of showoffy really. Finger acrobatics. I can't imagine how objective science via an oscilloscope will show this.
This goes beyond guitars. Piano, violin, clarinet... Stereo system. Years ago I went out to purchase a new french horn. That horn of all horns for me. Got down to 4 manufactures/models costing between $8-12,000 at the time. They all are fine horns as resale values represent. Still fine horns by todays standards. The one I purchased ultimately was because it was the most Friendly to me. Did what I asked it to do. Almost helping me play my best. Objective scientific measure? Not yet.
