Does this come in a left handed configuration?

I am glad to announce that the Ruler for left-handed is actually tested and should be released somewhere end of January!

One commenter stated that a note was missing from the pentatonic scale. Is this correct? Has it been fixed?

This is an excellent music theory tool. The minor pentatonic scales are set out on one side and the major pentatonic on the other. If you use this as a modal training tool or a CAGED system training tool it works very well. I got used to the semi tone interval being missing as it was clear what notes they were when looked at in the context of the key you are in. I would buy this in a New York moment even with this situation. Its a hell of a tool!!!

Why is this so pricey for a laminated piece of cardboard? And what’s the benefit over other cheaper scale tools?

If you want a piece of laminated piece of cardboard I can sell it to you for only $0,50 but if you want a piece of art, get my Sliding Ruler for Guitar! It took a long thought process and many trials and error before I could get to this result! You don't pay for the plastic, as you don't pay for the paper when you buy a book, you pay for hard work the author have put into it! Please, read the positive reviews I got for this Ruler and try it with a guitar in your hand and just go through the notes you see into it. You'll be amazed to discover new paths to your creativity and a new understanding on how your guitar works!

Did you fix the error on the chart or are you planning to fix it?

Yes, the error has been fixed! It only happened in a limited production batch! If this is your case, don’t hesitate to ask for a new one through our website.
