Guitar lessons at Artistworks is a great way to increase your knowledge and skill on the guitar.
I personally have a subscription to Rock Guitar with Paul Gilbert. Paul has over 10,000 video replies with his students! Even if you never submit your own video there are thousands to learn from!
I am also an affiliate for Artistworks. Using the links below will help support WeirdGuitarist.com in bringing you free guitar content.
In the future I may develop a lesson site of my own. But for the time being I can confidently recommend the folks over at Artistworks!
