Sliding Ruler - Magic tool for the practice of PENTATONIC, DIATONIC and MODE scales/Pentatonic Sliding Ruler for Guitar: The essential tool for ALL Guitarists

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 design2. 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.

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.

The slide rule seemed a tad pricey, but you only need one and I'm glad I bought it. It's brightly colour-coded and clearly shows the 5 positions of the pentatonic scales, both Major and Minor. If you line up the A note at the 5th fret [minor pent.] you will see in glorious red the shape and note names of the scale in that position - along with the shapes adjacent up and down the neck. Whip the slide rule over and you now have the C Major pent clearly displayed. Cunning or wot?For lovers of Greek architecture there are also references to Aeolian and Ionian [and other] modes - way beond this guy's paycheck to evaluate!All in all; a clever invention and a recommended buy!

Just sorry I didn't discover this earlier, would have saved marking out scales on pages.

If you play electric you need these patterns.

The idea is a great one. Unfortunately, the quality of the actual product is hugely disappointing. Very flimsy and has the feel of a teenager's school project. Shame it couldn't be better made as I seriously doubt it will last very long.

Mine is better even though I invented it over forty years ago. What a rip-off of my Copyright. They should do searches before making it, to honour MY COPYRIGHT!!! Mine is loads better anyway. Any Copyright Lawyers what to get involved?
