Is this correct? Has it been fixed?** A: 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!!! **Q: Why is this so pricey for a laminated piece of cardboard? And what’s the benefit over other cheaper scale tools?** A: 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! **Q: Did you fix the error on the chart or are you planning to fix it?** A: 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. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by M***D on 15 February 2026* Great product. Easy to learn. Easy to use.
