Was it the jaw-droppingly awesome polyphonic tuning that made tuning much faster, easier and intuitive? The bright LED matrix with auto-dimming that ensured maximum visibility? Tuning Magnet, the slowing of the needle as you approached the correct pitch? Maybe the MonoPoly technology that sensed whether you played one or six strings and instantly adjusted accordingly?
