July 27, 2011, 12:03:33 pmThanks Chuck. The megaphone sound is amazing. It's loud. It's rough. It's mean. I have no doubt that it adds to my "visibility." I can crack the throttle and see the person in the car ahead of me check their rear-view. In the city, when I get into a narrow street with tall buildings I'll wind it up and its just sounds like thunder.
