I'm debugging a GGG ITS8 tube screamer I just built and based on help from another thread, I may have a bad 3PDT switch (or I might've melted it when soldering). I get correct voltages at the IC pins and Q1 and Q2 pins. I get a by-pass signal just fine to amp, but no led or signal when the switch is engaged.
I've read in other threads to test a switch by using a multimeter on continuity, but I haven't seen a detailed explanation of exactly how to do that. Like do I need to de-solder the switch to test it or what?
Would someone please be kind enough to help with a detailed explanation of where I should have continuity exactly? Thanks.
