Most calls have a reed that is the same thickness from end to end. Through a special process, Primes has "shaved" the reed of this call so that the tip of the reed is much thinner and tulip-shaped. This allows the call to be blown with much less air pressure while giving you a perfect sound. It also has a lot of volume, which is needed for large fields or marshes. You will be amazed at the sounds you can get from the Shaved Reed Speck from yodels to the piercing hail call. Features: - Super loud, requires little air - Tulip-shaped reed from 6/1000" to 14/1000" thick
