In 2007 he started Chocolate Cake Productions with friend Jed Wardley to release his instructional DVDs. By June 2012 there are 11 DVDs available, including "Master The Major Scale", "Really Useful Strumming Techniques", a "Solo Blues Guitar" series, "The JustinGuitar Beginner's Course" and "Intermediate Method". Sandercoe also publishes a number of electronic books in .pdf format, including "Practical Music Theory", "The Chord Construction Guide" and "Understanding Rhythm Notation", as well as an ongoing series of instructional songbooks, to which entries include the Vintage Songbook, the Rock Songbook, the Pop Songbook, and the Acoustic Songbook.
A far as the other learning material goes (books and DVD) they both looked fine as far as readability and simplicity. Right off the bat, I did feel as though the whole learning system is more geared towards children (which I’m sure it mostly is) rather than adults. This comes from the color scheme, overall look and feel of the learning material, DVD content etc. Now don’t get me wrong, that doesn’t mean adults can’t use this product, it’s just an observation that I noticed during my first impressions.
