To power them all with a single Pedal Power 2 Plus:
To power the Superego use Pedal Power 2 Plus output 5 or 6, DIP switch set normal with one of the all black (standard polarity) cables supplied.
To power the Holy Grail use Pedal Power 2 Plus output 5 or 6, DIP switch set normal with one of the all black (standard polarity) cables supplied. Or, to power the Holy Grail
Neo with Pedal Power 2 Plus, use any output, DIP switch set normal and one of the all black (standard polarity) cables supplied.
To power the POG2 use a
Current Doubler Adapter, part# PPAP in any two 9VDC outputs and with one of the all black (standard polarity) cables supplied.
To power the Boss DD-20 use a
Current Doubler Adapter, part# PPAP in any two 9VDC outputs and with one of the all black (standard polarity) cables supplied.
For the remaining pedals, each: use any 9VDC output with one of the all black (standard polarity) cables supplied.
And, you'll need to use an
Output Splitter Adapter, part# PPAV with two of these pedals (I'd pair the LS-2 and TS-1).
Cheers!
