  • Master ALL Major / Minor Pentatonics 
  • Find them FAST in all keys, on all the fretboard 
  • Practice with a REAL BAND in video!
  • Innovative and easy DCLS system 
  • Strong foundation for Modes / Major Scales


Struggling to find your way on the fretboard?

You don't need just scale boxes!

You need an effective system to:

  • know what scale to use
  • see it quickly wherever on the fretboard in all keys

DCLS (diesels) is a complete modular system that makes it easy to learn and find scales at a glance on the guitar.
It makes pentatonics, major scales and modes, the 3 essential sounds of modern improvisation, clearly visible and interconnected on the fretboard.

Stop learning scale boxes, learn how to use them!

DCLS part 1 is about Pentatonics

  • the scale we all know and love
  • the scale all guitar playing is based upon
  • the foundation for all the more complex approaches

But do we know it well enough?

In this part you will learn :

  • Minor Pentatonics
  • Major Pentatonics (as a new scale but with the same boxes)
  • How to find all boxes on the fretboard easily
  • How to connect them
  • When and how to use them 
  • How to use the whole box, not only the easy spots 
  • The DCLS (diesels) System that will build strong foundations for more complex scales, like major scales and modes


All Backing tracks for this course are played on video by a 4 piece band! You can practice while you watch the video, it would feel like you're actually playing with 4 pro musicians, including me.

Why DCLS works

To be a fluent improviser you need 3 things:

  • Be able to see scales fast on the fretboard
  • Know what scales to use in various situations
  • Have the technique to express yourself  

My "Diesels" system will not only help you memorize the scale boxes, but also see them at a glance on guitar.

It builds on the CAGED idea, but makes it better:

  • works with minor and major pentatonics
  • works with major scales and modes
  • all scales use the same system 

It's modular, so you will only need 10 boxes to build all scales! 

In parts 2 and 3 you will also learn how to analyze chord progressions and know what scales to use, play over key changes and finally make sense of modes.
All with the same 10 scale boxes!!


  • Master Major and Minor Pentatonics
  • 3 hours of video 
  • 25 step by step lessons
  • 15 backing tracks w real band in video
  • Downloadable PDF with support material 
  • Clear explanation of all concepts
  • Innovative and easy DCLS (diesels) approach


I know the pentatonic scale, why should I take this course?

It is possible that you know the pentatonics but not as in depth as you would with this system.
It is quite common to use only a couple of boxes and not even across all strings. Sometimes you feel like you're using always the same few notes in the same 2 boxes. 
Furthermore DCLS is a modular approach, and learning or re-learning the pentatonics this way will build solid foundations to move up to major keys/scales and modes. 
In the end with just 5 minor and 5 Major reference boxes you will cover almost ALL used scales. 

What does DCLS mean?

DUAL CAGED LAYERED SYSTEM - and it's pronounced Diesels

What is DCLS?

DCLS it's a complete improvisation system that starts from pentatonic scales and works its way up to modes. It's an improvement of the CAGED system. There are a few areas where CAGED is a bit uneffective, especially on minor scales and DCLS fixes that. But unlike CAGED, DCLS is designed to work with modes as well.
It's modular, so you will have only 10 basic boxes, and everything else will build on these just by changing a few notes. 
This is unique and speeds up the process of understanding scales and modes, recognising them on the fretboard and learning their sound. 

Is it better than CAGED? 

CAGED has limits, especially in minor keys. The Diesels system builds on CAGED but improves its effectiveness, making finding pentatonics, major and minor scales, including modes...a piece of cake. 

What are part 2, 3 ? 

Part 2 Is about the major Scale. You will learn all the boxes but more importantly how to know in what key you are in so you can improvise properly. Also it will deal with common key changes and modulations. 
Part 3 will be about modes. The DCLS system is great with modes, let's say it makes them as easy as pentatonics..to memorise and as usual to see on the fretboard. Modes is where the DCLS system really shines! 
Part 4 When released it, will be about more complex scales, like modes from the melodic minor, altered scales and superimpositions of pentatonics and triads. 

If I buy part 1 now will I have a discount on the other parts? 

Certainly! The full course is available as a bundle HERE. But if you prefer to start with just this part, and then decide to purchase the entire course bundle you will have a proportionate, substantial discount!
