Fact is, most of these methods are probably pretty good, however, even the best of these are going to be limited in their ability to enable you to instantly recall notes, chord shapes, scales,
arpeggios, patterns etc. with zero hesitation…
Why is this true?
The answer is that any ‘single’ fretboard memorization method will train your mind to recall the information stored in your brain in a very specific way.
But when you are playing guitar, you will need to recall where things are on the fretboard in a variety of ways because the context in which you need to recall those things will be different from one musical situation to another.
Check this out it really works
You won’t have an “instant” way to recall all things on the fretboard for every playing situation.
To recall something INSTANTLY, your brain must be able to do it in a single automatic step.
In order to do that, you need to use not one fretboard memorization technique, you need to use many.
In order to do that, you need to use not one fretboard memorization technique, you need to use many.
So don’t look for 1 way to it, look for several good ways and rotate each technique every week.
