The instructor has to match you. Even if the nicest person, the style and direction has to meet you where you are.
My wife is starting to learn mandolin and had a teacher for a brief time but he would only focus on one thing the whole lesson, every lesson. He was trying to tach her a skill and that was good but after a few lessons, she had no idea why the discipline he was teaching was important. She'd ask where it applied and he wouldn't really say (it was a strumming pattern). So she stopped.
So, really....You have to get something out of it.
...and interesting that he wanted to have you 'stick with the artist's version'....Odd since Jimi made a career of not doing that...Hey Joe, All Along the Watchtower?
