You might think that being a guitarist you need to do that all, but I dont think while you are practising you need to play the same scale over and over for so many years(which you've already mastered). You dont feel like playing certain songs after you played it once. So what you play more to enhance the quality of your sound? ------please dont write me "practice more scales"....I am doing this for almost 8 years......I wanna know the most efficient way that you all follow to improve your playing.
As for me I prefer to practice more tricks and techniques rather than playing those lifeless scales.
