I plan on buying one of these because im getting alot of hum from my One Spot chain. Here are the pedals I run:

Boss Tuner
Boss Noise Supressor
Maxon OD9
Boss Chorus
Holy Grail Plus
Line 6 DL4

My questions are, do I have to use 2 spots for the DL4? If so, does an adapter come with it or do i have to order it seperately? Are any of my pedals a concern for compatibility with the Lab power? Thanks in advance.

The PP2 comes with the cable to powerline 6 modelers, it only uses one input (5 or 6 with the dip switch away from normal)
