One other thing ...... if you picked up the call in used condition, or from a store, it may be out of tune. If you're close to Port Clinton, OH, which is where Zink's business is located, they will help you personally if you go there ..... though I'd call first, of course. A minor retuning might be all that it takes. Also, Zink's pro staffers, at least in this state, will often put on calling demonstrations at various large retail sporting goods outlets. Perhaps there will be one near you, where your call can be checked out. And, finally, you may have a Zink Pro staffer near you who will help you out. You might contact Zink Calls and ask if that's possible.
The Money Maker is not a hard call to run if it's tuned properly, but the larger bell on the insert does make it more difficult to run if you have small hands.
