I've been a subscriber for years and think it's very much worth it. They keep improving on the site with new features regularly. I also take lessons. My musical tastes are a little out of the norm and teacher is older so most of what I want to learn is new to him. Printing up tabs ahead of time saves him the trouble of tabbing out the song while I just sit there. More time is spent learning. Yeah they're not all 100% correct but it's usually close enough to save time
