A new teaching resource has been added to the Lesson Materials section under the RES series. This new resource will give you simple fretboard diagrams to use to help teach scales and modes. You can also use the diagrams to come up with exercises and tests to check your student's level of understanding and application of theory. It's a simple resource but very useful.
Access the resource here: RES-09 Blank Fretboard Diagrams.
More resources under the RES series are available in the Lesson Materials Section.
