Terrible idea. You're gonna eventually melt/fry your PP2+, guaranteed. That and the following was confirmed to me directly from VoodooLab... Outputs 5 and 6 together can supply no more than 500mA combined safely. However, you can run a pedal that needs up to around 330mA on output 5, but then the pedal on output 6 needs to be under 170mA (again, 500mA combined). So putting 2 pedals that each require 300mA in outputs 5 and 6, is basically Kamikaze-in your PP2+.
