Myles,
Do you have any advice for running a Boss DD3 Digital delay through a Rivera Quiana effects loop? I followed the instructions in the Rivera manual, but can't get a good sound out of it. Its sounds okay through the clean channel, but unusable through the distorted channel. I used this delay through a Marshall Jubilee for a couple of years and it worked fine. It also woked great through a Marshall 30th Anniversary, which had a parallel loop, but doesn't sound good through the Rivera loop or straight into the amp for that matter.
