Just a quick post to say I am very happy with RUGS2. Along with RUGS1 it has helped my playing, my understanding of chord construction and my understanding of music in general.
I have had no music training, have no guitar teacher (other than this site and youtube) and have found both these products to be easily understandable and excellent value for money. I have no hesitation recommending these packs to anyone who is unsure about whether to purchase.
(great site too Justin)
