Thank you for the lesson and the slides 
Very interesting Justin. I’m heading towards the end of your Justinguitar.com Beginners Course and will probably be starting on the intermediate level of your course in the spring. I have to say that I’m definitely interested in the blues but funnily enough it was not my favourite genre. Things are changing for me in that direction! Just a quick unrelated question. Do you think it’s better to practice on acoustic or electric? For me it’s acoustic generally but electric for power chords and rock stuff. By the way, I liked the Roo at the back! All the best, William
Tagging @Richard_close2u who can be more helpful than me on this.
You have already learned some cales in the beginner course.
E minor pentatonic in open position - E-shape, pattern 1.
C major pentatonic in open position - C-shape, pattern 3.
A minor pentatonic - E-shape pattern 1.
Plus you have hopefully spent time making music with them, melodies, lead lines, even improvisation.
The 5 minor scales are some way off ahead of you and Justin has sage advice on when / when not to learn scales. https://www.justinguitar.com/guitar-lessons/when-not-to-learn-scales-sc-104
That said - you can learn, practice and play scales on either type of guitar. The big decision comes when you want to begin to play with string bending - that is largely an electric technique.
