Hi All .I have a 1963 Vox AC 30 head. The switch for the tremolo is on a bent piece of steel. The PO was certain that this was the original switch , but I have my doubts . The rest off the amp is Original , except for the electrolytic caps . I ve come across an old Egg switch , but dont want it if the bent/formed sheet steel one is the original. Anyone help out here ? Thanks !
