It's parallel. It's a Revision G, which all have parallel loops. Anything after '93 or so is parallel.

Personally I hated the Parallel loop in my DR. But I run an EQ in the loop, so that explains it. The pros is that your loop is useable and works better if you ask me. Others may disagree.
The cons is that you loose the footswitch capability of turning it off and on, so if you want a one tap solution to multiple pedals in the loop, you will lose that feature.
The mod is easily done, and easily reversed, so you can try it both ways to see what you like better pretty easily.
Are you sure about the footswitch thing? The original Rectos had a serial loop and still had the footswitch capabilities.
I think the 3 channel versions are the ones that lose the footswitching, and there's a mod you can do to the pedals to gain that back.
