I always had my action set about mid. After having read countless posts about lower action being faster, easier, whatever else, I decided to lower my action & one thing I have noticed is constant fret click. Doesn't matter how heavy or light I play, fingers, pick, slap or tapping. Every 2-3 notes & CLICK, pain in the bahookie!
I haven't found any advantages yet as my playing is just the same & can go up & down scales no quicker.
The bass could be a factor in how low an action you can have or maybe my truss rod needs slight adjustment (I do get fret buzz when I try & play the 7th fret on both the E & G strings together, limits my B minors).
