Single reed mayhem is upon us. Zink Call's new Green Top Rocker is clearly at the top of the food chain when it comes to top-end volume and pure and nasty duck sounds. Designed to shake the trees and produce the flat nasally sounds of an old hen mallard the Green Top Rocker comes down nicely on the bottom producing the softest of chatter and finishing chuckles and quacks. The new Green Top Rocker comes complete with hard case extra reeds and instructional DVD.
