Ive seen where some are concerned with the soundboard touching the inside of the pot. Ive never had that problem, but I have almost a 3/16 gap all the way around the soundboard. My shelf for the playing surface is only about 1/8 at best. My question is, should my shelf be wider than that and close the distance between soundboard and the inside of the pot? The calls, I believe, will kill turkeys, but just not getting the sound im looking for and what ive heard from some of others calls. Im working with 3" soundboards.
