IMHO, I like the idea of the blindfold test.
You wear a blinfold and someone hands you a series of guitars for you to compare the sound, feel, etc., without the visual aid. A lot of the way we think has to do with what we see and in the blindfold test, your other senses have to take over. Your brain processes information differently when any one of the senses is compromised.
Humans are often victims of the need for status. There is a certain status that comes from the hood ornament of a Mercedes Benz, the headstock of a Guild DV72/Martin D45, etc. We get locked in to what we see to the point of missing the more important aspects; e.g., how it feels, sounds, etc.
Like Billy Crystal's Fernando character on SNL, "It's better to look good dahling, than to feel good." :lol:
Just pondering over Friday morning coffee...nothing too serious. 8)
