Hello little socrates.
I admire your understanding of theory.
I have about 50 guitars and am building a recording studio.
I have been playing since the beatles came out in the 60's.
I have never used a power chord.
I don't think they existed back in the 60's
Or as you infer whether they exist at all.
I always thought people that used them did not know how to play the guitar or were lazy.
For the most part I never cared for bands that used power chords or how the guitar sounded in them.
I don't think Hendrix, Beck, Clapton, the Stones or the Beatles, Steely Dan, Dire Straits, Pink Floyd, Satriani
ever used them.
Van Halen did, and that is where I drew the line.
They took the perfect Rock song You really got me
and ruined it with power Chords.
I don't think the Kinks used Power chords on the original.
What do you think?
