20/20 slaving help?

[BlackIrish]

Hi,
I'm curious about slaving my 20/20 into the fx loop of my Marshall JTM-45 which has a series loop, I still want to run my rack processor and other fx in the loop. How do I do this? Also would I have to run the fx in the loop at line level now? Thanks for any replys

Just talked to Boogie they said it was one or the other slave into fx loop or use fx in the loop not both.
