Interactive Guitar Fretboard Visualizer

I built this tool because it didn't exist. I wanted an easy way to navigate through guitar scale patterns, chords, etc.. Prior to Fretastic, you had to use Google Images to sort through loads of low quality static diagrams.
Fretastic became quite successful, garnering thousands of users over the course of several years.
