I am looking at a slightly beat up ampeg fridge on my local CL for $250, but it's missing th grill cloth, possibly one bad speaker and the tolex is in rough shape, which I know is common, I believe it is late 80's vintage. I was wandering if anyone has ever put a metal grill on one, and where would i get one, or have one made. Also thinking about removing the tolex and replacing it with some leftover duratex I have laying around, maybe swap out the jack with a speakon too. Any thoughts? Anybody else do similar mods?
