I have a '64 Silvertone Twin Twelve, all original, just replaced tubes today. It has a ground lift switch....no grounded plug.
If I were to disconnect the tip of a 1/4 inst. cable on both ends, then jump from the other input on the amp to an unused insert on say a mixer or interface....does that ground the amp?
