Thought I would give a review on something different - a book.
I bought my copy of The Guitar Handbook, which is authored by Ralph Denyer, around 1994 / 1995. It is excellently written and has been my 'go to book' for advice and tuition for a little over 20 years.
This publication covers everything; from initial mini write-ups of internationally renowned guitarists', to the anatomy of guitars (acoustic & electric), music theory, guitar maintenance and customising, performance technology (some of the information is probably now out of date albeit still useful), and a comprehensive chord dictionary.
Not sure if this book is still in publication however, I find it to be invaluable. If it's no longer in publication, you might be able to pick one up on ebay or at a secondhand book store.
