It isn't that easy... When we are referring to a dead spot, we aren't referring to some imperceptable change in tone. I had a Special with a dead spot at the 12th fret g string...it was *very* noticable...you didn't need a scope to tell. I am talking serious drop in volume and virtually *zero* sustain. Thats a pretty big deal bro... Luckily, when I changed strings to .11s, it went away...
