Dude. I just joined guitartricks.com as a high bandwidth user for 5 bucks US and I've learned so much already. Seriously...5 bucks is a great deal. They've got a lot of cool stuff that I need to go through and it's pretty overwhelming. I don't plan on canceling my subscription for quite sometime. Honestly...I think it's worth every penny. I haven't tried any of the other sites you mentioned, but I'm sure they can't be as good. It's almost 1 am and I'm seriously considering staying up a couple more hours shredding until the day comes. Cheers buddy!

No...no I do not work for guitartricks.com. Honestly tho...that's a great testimonial. Somebody...make a note of it!
