I could be wrong but you may be able to daisy chain those 18v pedals off of the Voodoo Lab PPII+ using the voltage coupler cable and a daisy chain. I'm not absolutely certain on that so I would look into it or await confirmation. It would seem that as long as you don't exceed the current output you'd be fine.fer
For Reference; Voltage Coupler ("PPY 18v Cable"):
Daisy Chain (the one that comes with the Visual Sound 1spot):
The voltage coupler cable on the PPII+ essentially combines two 9v/12v (with the dipswitch away from normal) outputs into one 18v/24v output. The only thing is it doesn't double the current as far as I can tell.
By daisy chaining you could potentially power that whole pedalboard off the PPII+ alone.
Again I stress,...further research or waiting on confirmation.
I tried to find any statements in Voodoo Lab bumf that said that you
could not daisy chain 18v without any success,...but I'm just making a slightly educated guess.
As far as weather or not you can daisy chain 9 or 18v with the DC Brick, which is essentially a daisy chain in a box,...I can't comment,...
