I disagree with another reviewer here in saying Stuart Bull being a terrible teacher. I think Mr. Bull is a good and competent teacher. I am saying that not just by watching this DVD, but also the experience from watching his several other DVDs. I purchased this DVD recently from Amazon, watched it and found it very helpful for me to understand the concept of scale positions on the fretboard. I will adopt his method in my guitar playing. The only slightly confusing part is Mr. Bull uses the term "scale position" whereas other guitar teachers use "scale pattern". In other material, the term "position" usually means the position on the fretboard such as 1st fret, 2nd fret, etc. But I was able to figure out the difference without difficulty as he explained. His British accent doesn't bother me. England is the origin of the English language. I don't think we have rights to criticize their speaking. I am a Chinese living in the United States for 12 years. Therefore I am more used to American accent. But his speaking is totally understandable to me.
