Harley Benton PowerPlant ISO-5 Pro

I have been using this supply for over a year and it does the job very efficiently. I use it to power four pedals, both old (mxr phase 90, TS9) and recent (TC electronic sub n up, dark blood).

The one slight drawback could be that the main power cable (that you
plug to the wall) is a little short.

Otherwise it is virtually noiseless; there is no audible change when swapping from a battery to the supply, even for distortion and OD pedals. It is small and looks robust, and the necessary cables are supplied for standard pedals.

EDIT: after 4 years of use I have to revise my judgement. Having added two digital pedals, I see the limits of this supply. Now I use 6 pedals including a digital delay and a digital noise gate, and I can hear noise, and I am still well below the rated max. power. I can minimize the nosie by choosing which output I use, but I cannot completely suppress it.
