Possumal If I have to knock my teeth out to get Cronk's call to work, well, I think I'll use it for target practice on a fence post. LOL The tone break I am talking about is the call abruptly changes pitch. I can howl pretty well on other open reed calls but sure haven't got this Cronk call figured out. It reminds me of a Primos Hot Dog. It takes a lot of air and tone breaks a lot. At least for me it does. I have a latex reed E.L.K. Yote Howler that is very easy to blow and sounds great. It is not super loud but does the job.
