There are fairly profound differences IMO. Often I have witnessed many hunters use a long box in the fall where the kee kee it is noted for is perfect for calling back the flock once broken. A short box can have a kee kee as well, but typically not as pronounced nor does it have the range of a long box for this feature. Many sprinmg hunters carry a long box for locating as it is known to generally be a lounder call capable of carrying through the wind and great for bellowing across ridges and down and through hollers. A long box is wonderful for cutting, cackle fly downs and more ofeten are tuned to have a higher pitch or tone. The short box has gerat diversity, is easier to carrry and is normally, though it depends on the wood combos used not as loud as a long box. Purring can be done on both, but IMO and from my experience with customers they find a short box can purr easier with greater eas than a long box. The yelps are different with a short box having more of and slightly abreviiated break in the yelp and greater range in tone, often a deeper bottom whereqas a long box does break and well but tends to hold a longer and raspier yelp superp for an old nasty hen. Short boxes are also great for cutting and are also ideal for soft feeding sounds and whiny tree talk if you work carefully with your fingers along the sound rails to soften the sound. I would say clucks are about equal in both calls, but there again IMO. Wood combos...well there seems to be a few traditional combos for long boxes, but on a whole the woods are fairly interchangable and depending on the skill of the builder each can and should be tuned as the customer wants and to best fit the birds of the region
