So I have been reading about the polarity switch and prettty much everybody says to remove the “Cap of Death”. Well I don’t know which one it is or even if it actually has one. We have a 1959s first reissue made in 1988. It already has the 3 prong power chord that I’m sure Marshall had to put on by law for import to the USA. What I can’t tell Is if the polarity switch actually works. Here are some pics and see what you guys think.
