I hope HUT gave you a reed that will tone out low enough for a squirrel call. I told them the last lot they bought for squirrel calls were the wrong reed, and they told me they would refund my money if I sent the parts back, but really had no interest in fixing the problem. They said, "JC told us these are the right reeds for these squirrel calls." I told them they were not, and would not sound like a squirrel no matter how hard someone tried.
I also use the rubber bushings so I can drill my holes at 1/2". If you need any further help, feel free to send me a PM.
