Not sure if you fixed your problem or not....I am new here and stumbled across your post. I have a 5212, and mine does strange things unless I connect a cord between the send and return on the effects loop.

This means there is something wrong with your jacks.  Probably they are just dirty, but they could be worn out.

Probably, but now worth taking apart right now. I use it all the time with no problem.
