I had
Planetalk for a couple of weeks or so now. No gimmick, no tricks, no gizmo. Just easy to understand way to see your fretboard.
I've played guitar for years and learned quite a bit of theory. In fact, still learning theory, confusing as ever. Planetalk has organized it for me by showing me how to see my fretboard. So simple that I'm surprised that I didn't see it.
I should've got Planetalk years ago but I thought it's just another learn the guitar gimmick like the others.
It's not. It's the mindset worth learning. You won't have it any easier than this.
