Sliding Ruler for Guitar™ – The Original Guitar Scale Chart for Pentatonic, Diatonic & Modes! Perfect Visual Learning Aid for All Skill Levels, Beginner to Advanced Players. Practice with Ease!

This slid ruler really has helped to visually see scales and to help understand the basic structures of major and minor pentatonic and the root notes. The YouTube videos also are a great companion and tutorial to understand how the ruler functions. The manual is also beneficial but takes a moment to grasp the details.

Very nice and useful! I love this ruler👍🏻🤟🏻❤️🎸🥁🎼

It's a great way to see how the caged system works with the scales. It's an excellent learning tool; my only complaint is that the font needs to be bolder so it's easier to see.

First off, this is probably THE fastest way for you or a friend to start jamming (being able to improvise in any key). Seems like a missed opportunity to have major root note side be diatonic. This would not only show what every note is of all the modes, but would also be a great way to show the spelling of chords. I would have had the flip (relative minor side) side be the minor pentatonic side since it is so close to the blues scale. Nice that the major and minor roots are outlined, but I would have liked to see minor be an outlined circle and leave the major root as a square on both sides(consistency).

I love this device. What minimal music theory I learned was always demonstrated on a piano - but I play guitar. I fundamentally understood majors and minors and kind of grasped 3rds, 5ths, and 7ths, but it never all fit together before. THIS has been the tool that I needed to help my brain make all the connections. Now, the CAGED positions, as well as the Triad exercises, pentatonic scales, and diatonic scales - shoot, this even fits in the blue notes!I don't know how to describe it, but before, each thing I learned stayed isolated in my brain. Now, it all fits together, and it is making me a much better guitarist!The compact size is actually great. But (being old enough to have actually used a mathematical sliding ruler in grade school) my old eyes would love to get one at 1.5 times the size. Heck, to be fair, I guess I'd pay 1.5 times the price. lol.I love this tool!

There is not clear information on how to use the ruler, on the instructions says that at the web page there is more information and other languages for the information, and it is not true.disappointed... wanted the information in Spanish, if this is a market you want to reach... you need the Spanish information

Excellent quality!

Excellent, A++ learning tool for pentatonic scales, diatonic and minor scales, blues scales, and all seven modes. If you learn these five shapes backward and forward and inside-out (each shape is a different color on the slide rule), you will be the master of your fretboard. I bought it primarily to help me unravel the Mystery of the Modes -- I've tried several different ways to do this, but none of them are as visual, clear, and simple as this slide rule.Is it worth thirty bucks? For me, absolutely yes. I've spent more than that on flash cards and posters, and none of them have helped me half as much as this slide rule. Yes, it's $30 for paper and plastic -- but you're paying for the careful thought and planning that went into the layout and design of this very useful teaching tool.Customer service is also superb. I received a defective ruler (a couple of the cutout windows were missing). I contacted them, they said they had a defective run, and would send me a new one as soon as it was available. Took a couple weeks, but it got here, as promised. Well done!The con's don't matter very much: 1) It smells funky, like the mothballs and cedar in my grandmother's closet. I think it's the laminate coating, on the inside of the plastic sleeve. The smell fades after a couple weeks. 2) The instruction sheet crams way too much information into a small space, and isn't all that helpful. It would be better if they cut it by about 50%. The tool is so simple, though, that anyone who's already been exposed to fretboard maps won't have any trouble at all.Thank you, Rise & Shine -- you've made me a happier guitar student!
