If you’ve ever struggled with memorizing guitar scales, improvising fluid solos, or navigating the fretboard beyond your usual comfort zones, you’re not alone. The vast world of music theory and scale patterns can be intimidating—even for seasoned players.
But what if mastering pentatonic scales could be as easy as flipping a deck of cards?
Welcome to FretDeck, a fresh, visual learning tool designed by Guitar Freaks Blog founder Justin Comstock, now live on Kickstarter. This project is more than just a deck of cards—it’s a gateway to better improvisation, soloing, and understanding your guitar like never before.
Let’s dive into the details of what Guitar Freaks Blog offers, what makes the FretDeck unique, and why this Kickstarter campaign is gaining attention from guitarists around the world.

The Pentatonic Problem: Why Most Guitarists Get Stuck

Let’s face it—pentatonic scales are foundational. They’re used across blues, rock, country, metal, funk, and beyond. But despite their importance, many guitarists hit a wall with them. They:
-
Memorize one or two box shapes
-
Struggle to link scale patterns across the fretboard
-
Avoid certain keys due to unfamiliarity
-
Improvise within narrow comfort zones
Traditional teaching methods emphasize diagrams and theory but often fail to give students tactile, visual reinforcement.
This is the precise problem FretDeck aims to solve.
Introducing FretDeck: A Visual Pentatonic Scale Learning System

Now featured on Kickstarter, the FretDeck Pentatonic Guitar Scales deck is the second iteration of a concept Justin first launched in 2016. It has been redesigned and reimagined for modern guitarists seeking a better way to learn.
What’s Inside the Deck?

-
60+ Cards: Each card displays a pentatonic scale shape across a fretboard visual.
-
All Keys and Modes: Includes major and minor pentatonic scales in every key.
-
Color-coded positions: Helps identify patterns and transitions between positions.
-
Practice Prompts: Some cards include creative improvisation exercises.
-
Bonus Courses:
-
Pentatonic Secrets Course: Shows you how to use the deck with 6 improvisation prompts and jam tracks.
-
Chord Secrets Course: Teaches how to connect chord progressions with scale choices.
-
Who Is This For?

-
Beginner guitarists who want a simple, structured approach to pentatonics
-
Intermediate players who are stuck in a few familiar boxes
-
Advanced improvisers looking to unlock new modal approaches
-
Teachers who want a visual tool for student engagement
How Does FretDeck Work?
FretDeck isn’t just for memorization—it’s a practice tool.
Here’s how you might use it:
-
Shuffle the Deck: Pull a random card and play the scale pattern across the fretboard.
-
Play a Backing Track: Improvise using the selected scale in context.
-
Apply Modal Thinking: Use a card to shift your playing into different tonalities.
-
Combine Chord + Scale Cards: From the bonus courses, apply chord knowledge to your lead phrasing.
Each session with FretDeck becomes a game, lesson, and jam all in one.
