I was given an old Gibson G20 (previously incorrectly given as B20) guitar combo amp. It's solid state, 10 inch driver with a spring reverb. Date of manufacture unknown. When I opened the back panel to look at the electronics I noticed white fabric lining the inside of the electronics housing. My guess is that it's asbestos to contain a fire if the amp should smoke itself. I hope I'm wrong because asbestos is pretty messy s#!÷.
Does anybody have any idea what this material is?
Thanks in advance.
