VH4 parallel loop hum issue

I've started to use my parallel loop for effects. When I crank the parallel loop volume I get an annoying hum, even if nothing's in the loop.
I've been told it might be a ground loop problem in which case I'll try a palmer pl101 to get rid of it but I wanted to check first.
Anyone know a fix?
Thanks in advance.
