Thanks for the suggestion. I tried #1 and #2. For both situations I get a signal when a block is set to any send/return option except FX Loop 1 and 2. However, when I insert a drum machine into Return2, it works, whereas in Return1 it doesn't, so at a minimum, Return1 appears kaput. My unit is long out of warranty, and I'd rather do without than pay for a fix, so I guess I'll just open it up and look for a bad connection. Thanks again.

I can run external pedals via send/return 2 (Loop FX 2) but not via send/return 1 (Loop FX 1). (Actually, I'm not sure that send/return 1 has ever worked--I only first tried using the send/returns recently.) I've updated firmware to 3.71, no difference. All I can think of is a hardware problem, but I'm open to suggestions!
