Whether you’re just starting or you’re a master shredder, there’s something for you. I haven’t used any of their lessons, as I found them after I’d been playing for a long time, so I can’t attest to the lessons themselves, but going through their options they have a lot of lessons for learning scales and practice exercises, and can build your own library of tabs and lessons so you don’t have to search for the same song over and over while learning or refreshing on it. A lot of the features are free, so even without the membership it’s still a great resource for any guitar player.
For me, the meat and potatoes is in the tabs library and the pro tabs option that you get with a membership. It lays out the full song in bar format and you can have it play a midi tone version of the song from what’s in the tabs so you can hear the notes and watch the tracker to know exactly where that tone is supposed to land with proper timing. It helps so much more than straight tabs, as you can see and hear where and how the sound structure comes together for things that are hard to translate when you’re just looking at numbers on a page trying to figure how to play those with proper timing and placement, especially for complex things where it’s a million notes in a cluster with nothing to translate timing.
Like any community tabs archive, not everything is always a correct tablature, but the selection is better than everything else I’ve dug into. I’m not sure what the monthly is, but I see the same lifetime deal I got pop up from time to time.
