My brother and i got into a very heated discussion about guitars, instruments and specially prices. One of us are saying "Prices are the measurement of quality of the guitar. Someone using a Squier or Epiphone are lower-level then Gibson or Fender. And studios use only their instruments, for CD's recording you can't use yours." Other thing discussed is about quality of one guy. The strokes guitarrist, Nick Valensi had a signature Epiphone. My brother said: "he had a signature epiphone because he's bad. If he was good he had one Gibson signature." after i replied " well, is because nick use a Epiphone, since he started." he answered "Well, he's stupid. Gibson always would be better than epiphones" Well. Is this something real? I wish to understand that. If he is right, i'm wrong about almost everything i belive in music, so give me what are your thoughts, please!
