Hi, I need specs on a true bypass type of switch. The blue one that you show looks correct. I need it to fit a Marshall Shredmaster, which is a PCB mount that then protrudes through the top tin. The contacts are 4.5mm apart vert and 5.7mm horiz. The broken switch that I have removed look a great deal like those that I have commonly used for true-bypass on crybaby’s. Please advise, Doc.
