Guitar Chord Compass

This Guitar Chord Compass is a mechanical fretboard decoder for seeing how chord shapes connect and move through different keys. Slide the tool to reveal positions across the neck, then use the accompanying theory book to explore the CAGED system, triads, chord construction and inversions.

It is a screen-free, battery-free learning set for beginner through advanced guitarists. Use it during home practice, songwriting or lessons when you want to understand the fretboard rather than rely on memorizing one isolated shape at a time.

Why You'll Love It

• See the CAGED system — The movable layout connects familiar shapes across the whole fretboard.
• Build a wider chord vocabulary — Use the tool to explore more than 1,000 chord possibilities and movable variations.
• Understand triads and inversions — The visual reference and book show how smaller chord structures relate across the neck.
• Learn without electronics — The mechanism needs no screen, battery, app or update.
• Turn theory into a fretboard map — Chord construction and position logic become something you can point to and test.
• Support teaching and songwriting — Use the same physical tool to explain a concept or look for a fresh voicing.

How to Use It

1. Choose the chord or key you want to explore.
2. Move the mechanical slider until the selected information is aligned.
3. Read the chord shapes and positions shown across the neck.
4. Use the book to study the CAGED logic, triads or inversions, then play the positions on your guitar.

What You'll Learn / Explore

Explore the CAGED system, triads, chord construction, inversions, movable shapes and fretboard logic. The compass helps you see how a chord continues beyond the open position, while the book provides the structure for turning that visual into practical understanding.

A Complete Learning Set

The compass is the fast, hands-on fretboard map; the book is the deeper guide to why the shapes connect and how to use them.
