Hey Styler, for a beginner a simple box call is probably the easiest to use and it doesn't have to be a custom call either, one right off a bass pro shop wall will get the job done as long as you learn how to use it.
A easy to use slate call is also a good one to use although I had issues using one when I started 28 years ago. I found the slot type slate call was very easy to strike and replicate the turkey good enough to sling a few over my shoulder.
I've got alot of customers in the mid-TN area and have hunted there myself for the last 3 years and I'll tell you they are birds that love to answer but don't always come to the call so don't get frustrated with 'em. Get above 'em.
If you wanna try one of my MadHatter Calls, especially the 20 dollar pocket player, check 'em out at www.turkeycall.co
Good luck huntin'.
