And my turn to echo the other guys.

I am a new full access subscriber here at Guitar Tricks but I had enough time to see what the site can offer (reference, courses, tutorials, tips, tricks, active forums, etc.)

I think that as long as you take it seriously each day using GT as the main resource to learn the guitar can be possible. Sure that using both the site and a private instructor is a great deal. But again I think if you are serious and dedicated to the guitar and to GT it's possible to progress very well here. If you have in your entourage a person who is an intermediate or an advanced player (like a friend or a family member), ask if he/she can watch you play live for anything wrong. This way it's a free complement and combined with GT low cost, you can't go wrong to learn the guitar!

That's my point of view.

See you guys
