Why the pedal makes the difference

«What I like most is the footswitch: not only is the laser integrated, it also allows me to change the light settings with my pedal to enhance visibility and play with the contrast. My absolute favourite feature of the pedal is the luxury of being able to switch between fluid and air (and back, and back again...) with my foot.» (D)
