I've been playing about 2 years using a DVD based guitar course, but I'm thinking of signing up for some online lessons. My course while good, is a little heavy on music theory and light on let's play something that's a rock'n. At this point in time I travel too much to worry about setting up lessons with a flesh and blood teacher. These two sites have top ratings. Which would you choose Jam Play or Guitar Tricks? Muchas Gracias.
