so I recently got an hx fx and I want to integrate it into a few pedals that I already have, maxon od808, boss ns2 and dunlop wah, nothing crazy. I have the hx fx currently in 4CM in to a 6505 mh , but I am not sure where to put my od, ns2 or wah, I would like to know how to have the ns2 in the 4cm method as well. before I got the hx I didn't have a lick of ground buzz with my ns2 in 4cm. hope any of this makes sense, I'm not quite sure what I'm doing. Thanks In advance
