Never played guitar before. I love it. Able to answer (most) of the questions correctly, and this really helped me learn the mechanics of a guitar. Good job.

The strings and notes sounds incorrect. Get a real guitar listen how the notes are really sounds and fix it. Also would be a great idea to build in a 6 string bass mod.

As others have stated, this is an awesome tool to test a guitarists knowledge of his craft.
It really keeps you on your toes and let's you figure out how well one knows their stuff!
One thing that I would suggest is having an option to angle the guitar neck at a slanted / various other angles because when playing I hardly ever view the neck in the way it is displayed here.
Other than that, this is a great quiz, and I applaud you for your contribution!
Keep up the great work!

I agree with Biggyzoom. It's really helpful for testing your knowledge of notes and frets. The only thing I'd like to see for an improved version is alternate tunings, and I bet you knew someone would say that eventually. The bands I'm in both use non-standard tunings (one is half step down; the other is dropped D whole step down), and I'd love to be able to test my knowledge on those tunings as well.

1380 first time on master. Well, what's there to say? This is a good tool for testing your fretboard knowledge. Thanks for making it.
