I tried to use a teacher when I first started playing. I'm generally self-taught, with everything, but I thought it would be a good idea, to get me started right. Selecting the right teacher is not so easy, though. I didn't have enough experience to select based on much except how far from my house they were. This guy had apparently been a pro player, but now he taught lessons out of his home, while his wife worked. I think he mostly taught kids, not adults. And he seemed bitter about ... something. I heard endlessly about how good he was, and every time he'd demonstrate the simplest thing, he'd over play, confuse the issue, and waste time. Dude! I hardly knew my basic cowboy chords at that point. In short, he was a horrible teacher, IMO, with a huge chip on his shoulder when it came to teaching adults. Any question I asked was taken as criticism, somehow. I stuck it out for 8 or 10 lessons, then hung it up, went home and started teaching myself. Not as effective, most likely, but at least it was comfortable ground for me. Fortunately my only goal is to play for personal enjoyment. If I wanted to be a great player, I'd be missing out with just li'l ol' me as a teacher.
