Gibson - some are good, and some are bad, just like with Fenders, Schecters, etc., and I oughta know, I've owned guitars from all 3 brands. Glenn's channel can be pretty interesting, but at times, it meanders into "all modern metal tones ala Trivium, 6 Feet Under, etc., all the time", including the type of gear used to play that stuff. As a longtime listener & player of metal (along with other forms of music like jazz, folk, country rock, and straight-ahead rock), that gets kind of boring for me. I usually want something new and fresh, not what's flavor of the month.
I read an interview years ago. I can't remember what guitar player made the statement, but it's stuck with me ever since I read it:
"If you listen to only one kind of music, your music will sound derivative. Listen to all kinds of music, and you'll create music that is unique, and sounds like you" (sic).
I feel that way about gear - everybody and his dog plays the same "appropriate for the musical genre" gear. It tends to result in guitar tones, that are the same old, same old.
