Excellent to understand the guitar fretboard
Incredible tool for guitarists. Exactly what I was looking for to understand the patterns and how everything is interconnected...I wish there were two sizes, one larger one and this size but this is perfect for general use. Excellent readability and Ease of Instructions. Could include more video instructions as apart of the training :) on how to use it. Very intelligent and thank you for creating a wonderful product!

Excellent Tool!
I'm a low intermediate student, but learning a lot. This tool is excellent! I've been learning theory too, because I want to know, and this tool is part of my journey to memorize the guitar neck and related chords/triads. It's a smart tool with some instructions to boot.

Decenter Rule - Beware Revision Might Be Available
Decent product, a little too much for what it is. Had to return it because before fully opening there was a sticker on the outside of the product with a "correction" attempting to fix a print error on the actual sliding ruler...unfortunately I don't want to have to reference a sticker to see what needs to change or take a sharpie and update the ruler. Just not worth the risk for me to try to learn on something not accurate.

Ingenious Device for Learning Pentatonic Guitar Scales
One of my goals is to learn major and minor pentatonic guitar scales to be able to jam with others. I have seen many SEPARATE diagrams for scales, but having multiple pages is unwieldy, or too small if multiple diagrams are on one page. This solves learning maj and min pentatonic scales for me. Very ingenious and a good value in my opinion. The accompanying instruction sheet was very helpful as well. I haven’t seen scale positions identified like this in any of my online instruction searches before. NOW I get it, thanks to this handy device. If you are learning guitar, specifically scales, I would definitely check this out; worth way more than a fancy coffee at a coffee shop for me.

At the risk of sounding stupid I don't think they are counting frets right
I'm a little leary of investing my time when on the first page they're telling me to play an Em at 033000..

It makes it make sense 🔎
Why did you pick this product vs others?: This is what I needed to open my eyes and see the fretboard in a really useful and fun way. It makes it make sense and strengthens other areas of playing. Bravo 👏

fantastic little learning aid, nice and clear with some instructions too I would recommend this for beginners, advance beginners and intermediate players nice to have on hand when practicing. and to the guy whining about copyright - 1. the product is massively different to your design and you cannot copyright the content as you do not own the musical scales, you could only copyright your slide mechanism, but this one differs to your design 2. there is nothing stopping you mass producing and selling yours on here as you clearly have had this for many many years so you have lost out due to a lack of motivation or business initiative. 3. its never too late, so take it upon yourself to get your product out there.

El producto llegó en el tiempo esperado, empacado en un sobre de papel y posteriormente en el sobre plástico de Amazon. Sin ningún problema. La regla plástica muestra las formas de la escala en el diapasón, y a medida que se mueve el cartón interno, transporta las notas de la escala. Es una herramienta muy práctica para ensayar, memorizar y estudiar. Un amigo la vio, y de inmediato me pidió el link para comprar la suya. La recomiendo para cualquier estudiante

This useful guide measures only 11" x 3" and has the five major pentatonic scale shapes and notes colour coded on one side, and the five minor (similar) shapes and notes colour coded on the other side. Though the major and minor shapes are the same, the root note changes. Very easy to read and the scale root can be set to any note on the major or minor side. Set note G as the root on the major shape side, and note E automatically appears as the root on the minor shape side. The five colour coded shapes are very clear and easy to follow. Also indicated are the missing notes to make the diatonic scale in any key, the minor 3rd in each key for the "blue" note, the seven modes, and the notes shared between scale shapes. Much more convenient than having to fumble through a book. You can practice with this on your lap with all the necessary info in front of you. My only gripe is that the enclosed instructions are not the easiest to follow, though once sorted out, the shape guide is very easy to use. Very clever and useful. Probably a wee bit expensive, but it certainly works.
