Its an mrce, thats the wireless wallmart voice changer board stripper out of the unit and I bought two AA battery holders to hold 3 batteries so I had room in one to put a on/off button in it.
I just used a hardhat liner, I didn't want padding in there. I live in Florida, it gets hot, I wanted as much room for air to circulate as possible. I have to get some fans in there before summer hits.
