TDPRI crew, I built a custom cab for a blues jr. It went great and I could not be more pleased with the result. I am now converting a custom cab I made for an EVM 12L into a combo. The cab is made out of Baltic Birch and I am converting it to accommodate the electrical guts of a Peavey Classic 30. I was going to cover the wood inside where the amp is with Aluminum or copper tape to protect against outside interference and protect the wood. Good Idea or a waste of $$$ and valuable time? Of course the Peavey cab was some flavor of pressboard. It was also painted black inside, perhaps to match the black tolex outside. Is the black paint covering inside a flame retardant or does it protect against heat? Is there something you recommend I put/apply inside the cab?
