The knowledge of scale patterns will not make you a good soloist, but it will help you to become one. You should be able to play them up and down the whole neck. Be aware that there are countless scales that would fit the part of the chord progression you are soloing on. Many years ago, a great player told me, that you could play whatever tone you want, you just have to make it sound good . That statement has really impressed me, because it is right, but nobody has told me before.
Every tone has a certain relation to a chord or chord progression in a certain context.
This is an advantage of those insturments, but may result in boring solos. This way you can easily fill up the time, til you have the next great idea, but in excess it will please neither you nor the audience. My relationship to the blues scale is pretty much conflicting. It is easy to learn an works well on many things, but it is adictive. It sounds good, it feels good and it tastes good, but it is kinda limiting in long terms.
