Very compact and powerful, excellent with high power and 'normal' pedals
I use this to power my 3 Strymon pedals and my midi/loop switcher. It's built like a brick: really solid, and can be used with all types of pedals. Even though it is not recommended to, I have used one or more of the power outputs with a daisy chain power supply lead to power many more than the 4 pedals this unit is supposed to power -with absolutely no ill effects or background noise/hum. Each output supplies up to 400ma at 9v, so there's more than enough to power pedals on a daisy chain as long as this total isn't exceeded. The unit does not have an additional courtesy power outlet (unlike the Pedal Power Plus 2 unit) but it can always be plugged into the one on the Pedal Power Plus 2 to reduce the number of main leads going into your pedalboard. There is what seems to be a small fan inside for when the unit gets really hot, but I have neither seen nor heard this in operation, and can only assume the unit doesn't generate much heat, or that the fan is so quiet as to be undetectable! All in all a great unit and solution for power hungry effects, and being the same size as the Pedal Power Plus 2, (only slightly shorter) using a pair of Pedal Train mounting brackets it can also be fitted underneath your pedalboard (Pedal Train).
