I' ve started to make a few custom calls, friction calls, glass over glass, glass over slate, slate over glass, etc. I have made four so far, and they came out great and also sound excellent. I am going to to start making more as time permits, but I need to come up with some good " Custom" Names for them. I know with all of ya' lls turkey knowledge and lingo you can help me come up with a few good names. As I make a few more, I' ll post some pics to let ya' ll take a look at them.
