1. Whenever I hit Rec button, I'm going blank keeping forgetting what's next note, making mistakes etc. Is recording only way to fight this?
2. Power chords vs my thumb. I came to an electric guitar from the old days, playing the classic and acoustic guitars of a very bad condition. I mean, string action like a centimeter was not so high So yes, I know I need to teach my muscles to relief my hand. And in most cases I learned to use a proper position, but for some reason, when playing power chords, I'm again pressing my thumg on the neck like crazy... after few minutes it's soring.
I will post you a simple example video of me playing the song, which cannot be played at music stores It's double tracked, so even in this simple example you can spot differences between channels, which means I didn't played them exactly the same...
So, what should I do, to correct my left hand positioning? In 1:24 you can see I switched to a relaxed position, but I was using only one finger to press two strings. When got to a full powerchord, I again went for this "classic" position.
