I use 10 inputs and two 9 v 12V without worry (even plugged all together!)
I saw quine artec pedals breathed not trust me, if it's on my pedal-board for two years and it works!
list of purpose supplied:
-Mxr super comp
-Mxr carbon copy
Mxr cae wah-M404
Double-mxr distortion shot
-Ibanez tube king (it worked but the sound was better with its own power supply!)
Vl-effect od one
-Fulltone OCD v4
-Tc electronic nova delay
-Tc helicon harmony gxt
most of these pedals have been connected together this power supply without any worry!
I even fed 2 tc electronic (nova delay and Harmony gxt) each 12v its the fact!
the only pedal with whom I had a problem it is a vl effects (fat Vintage bullit booster pedal deemed very difficult fed)
this is my experience with this pedal!
I always use!
