Synergy issues with a Bogner Atma series effect loop

[tdan71]

Hi,
Would anybody know why synergy wouldn't work a Bogner Atma with a series effects loop? I snatched one at a bargain price and I can't get the Synergy to play through it.
I’ve also tried plugging directly into the effects loop return to no results.
Thanks

Did you try a pedal in the loop to at least verify the loop is working?

loop return is a straight path into the power amp input must not be a signal reaching it
