Genius is a word too often tossed around in musical circles.
I'd like to be able to tap with my action this low without buzzing.
Ideally, an instrument used for touch playing should be an electric with an accurate neck, frets in good condition, strong pickups, and good sustain.
Producing the sound in this way is easy. But mastering its awesome and unexpected possibilities is another matter.
The essence of tapping is this: By hammering the string against the fret board with your finger, you can produce a note with one hand.
How low must you set your action ? Extremely low! If the distance between a string and the 12th fret is greater than the thickness of a penny, it is probably too high.
