For my Jerry stuff I go out the effects loop of my Mesa Lonestar Classic to my MC50, from there to my JBL cab. Works fine.
I don't know how critical it is, but I make sure to keep a speaker plugged in to the Mesa combo so the power section sees a load- even though the signal isn't going through the power section. I can't remember if that's more important with tube or solid state?
