This Guitar Scale Compass is a hands-on way to see how scales are built and how their patterns move across the fretboard. Slide the mechanical tool to a key and reveal the matching scale information, interval formulas and relative minor relationship—without depending only on memorised finger patterns.

Hey guys - it’s exactly what I need to transition from random noodling to structured noodling. Very intuitive and easy to use. The blues note is a great feature to mix up the riffs a bit! I had trouble finding the blue dot at first but now all good. Thx Kev

I have both the scales and CAGED products. The books are well written and easy to follow with great diagrams. I really like the sliders, much better than a computer screen or app.

Loved it! Easy to read and learn. Definitely a must have to expand the understanding of the fretboard.
