Hello, Can there be anyway to improve my guitar technique? I play rock,metal etc. ( I think I'm going to go Jazz instead of staying with power chords forever)

I have been playing for over a year and know basic notes in 1 position,second and know keys and some scales and W,W,H,W,W,W etc

Thank you.
I know it's not a very original idea on here, but have you tried justinguitar for lessons?

Falling short of getting one on one lessons, I reckon this may be your best bet.
