Just picked them up cheap and getting started in this pedal fun.
BURN THEM! BURN THEM WITH FIRE THEN NUKE THEM FROM ORBIT! IT'S THE ONLY WAY TO BE SURE!
As you might have noticed I hate perf board. I never manage to get a perf board circuit working. If pcb is the easiest to build, as you only have to solder the connections, vero becomes more difficult as you have to make some of the connections and disconnections as well, with perf you have to do everything. There's a lot that can go wrong and probably will go wrong. And which will drive you therefore insane as well. So now you know why they were so cheap in the first place.
If you persist in this exercise of masochism, one word of advice, do not bend and use the legs of the components to make the connections on the other side as well. Just solder the components in place, cut the legs off and only then use your leftover clippings to create the connecting circuit. No greater pain in the ass with a perf circuit then having to desolder a component and with it a part of your circuit as well.
