Funny you posted this, in my YouTube feed this morning was a Panama guitar isolated video. All you heard was Eddie playing the entire song.
Awesome rhythm work. Sounded like casual playing instead of the typical note, pluck precision in many songs today.
Ultimately the ‘best guitarist’ is really just someone picking a favourite band/style/image. People say Brian May is the best guitarist in the world. No.
All the fret-aerobics aside (which gets old) that is where he shines, just what you mentioned. His chords, voicings, rhythm, writing, etc...
You're right, there really is no "best guitarist" only a favorite... Of course some are better than others, Im talking about when the top echelon are compared.
Like when people say "Clapton is better than Beck (and the other way around).. Nonsense...
