Some people say that good guitarists are the ones who know when not to play. Others say that you shouldn’t play fast because you’d lose the feel and are showing off. What do you think about that?

I would not say that because it takes a lot of practice and discipline to be able to play fast and there are many guitarists who play fast but still melodic and are great to listen to.

For me, a good guitarist is one who knows how to play as required.

You should be able to play slow and simple when required but you should be able to play fast too when it’s needed.
