Bigger power supply for effect pedals from CIOKS with 7 outlets. All outlets are with well filtered, regulated, common ground 9V DC and yield a maximum current of 600mA. Good choice for a slightly bigger setup or board, but with no exotic pedals with non standard operating voltage. Big John is able to supply the Mod- or TimeFactor Eventide pedal, Alesis FX or Octavius Squeezer from Chunk Systems, just to name a few higher current 9V DC pedals. A few pedals from Moog also need 9V DC with a quite high current, where the Big John would be a good choice.
The red Power LED shows if the power supply is connected to mains. The green Check indicator warns you about overload or short circuit. A glance and you know everything is all right.
