Yeah, everything I know about guitars I didn't learn from anything related to actual bands. It was all through incidental TV/movies and whatnot. Maybe a little learned from musicians saying a little about it before performing.
Also I don't think I've ever actually looked up anything about any band, nor many musicians, at least not in relation to my listening to the music (sometimes other reasons, like hunting up similar bands or whatnot, though). Certainly not enough to know anything about their preferred instruments. That sort of info adds absolutely nothing to music to me, and I don't actually give a damn about who makes the music, just the music itself. So :V
Honestly, the concept of researching a band is almost foreign to me. I mean, discography or tour route maybe but... why anything else? It probably helps the concept of a favorite band/musician is equally foreign to me. Like. One? What the hell. That isn't possible. There's probably two or three dozen tied for first (most of them from entirely different genres), several times that tied for second, and another order of magnitude tied for third. And all of them are actually in a squiggly non-state of ranking where they're all in a cloud of "listen to this". I mean, I'd go homo for Tchaikovsky even if it meant a sex change, but it's less his awesomeness than the generalized fog known as "Eastern European Composers".
I just... don't comprehend the concept of researching bands I like. Or actually liking bands, really. I like music. Bands are of interest strictly to the extent they continue to produce it and are likely to produce similar quality/sound.
Also I probably shouldn't be trying to make a coherent point on the subject when I both don't really have one beyond vague noncomprehension and am trying to do so when it's four in the morning. So enough typing, have at thee.
