A few folks have written in asking about the chord and scale diagrams, and what software is used to create them. I can’t say enough good things about Neck Diagrams software — it looks great, very easy to use, lots of excellent visual capabilities and customizable features. It features a really cool Scale Generator, that does most of the work for you, and the notes can be set to show interval, note name, or fingering.
Neck Diagrams is very easy to download and install, and again is about as user-friendly as you can get. On top of all that, it’s very reasonably priced, and their support staff are fast and responsive to questions and emails. Check out their free demo and see all of the features for yourself.
