This is the first plug-in I've seen that deliberately emulates a ground loop. I can't help but think this emulator is one big April Fools joke. 
That's how I feel about tape sims and console emulators in general. Emulating a ground loop makes about as much sense as emulating channel crosstalk.
I'm still waiting for the tape sim that gradually alters the pitch of the project to simulate stretching, rolls off the highs and inserts random dropouts to simulate flaking, and bleeds the kick and bass into adjacent tracks if you let the project sit for a few months. Let's also make sure the Rewind key takes 20 seconds to work and doesn't always stop at the same place. Or the ultimate simulation, the one that randomly "breaks" and spools the virtual tape out onto the floor, requiring a virtual splicing block and razor to continue recording.
