I have owned this pedal power unit for a couple of years now. It was ok at the beginning, when it didn?t have to power a lot of pedals, and they were all simple 100mA boss-like pedals. After a while, the pedal collection grew, and some of them were replaced by more demanding ones like strymons.
That?s where the GBus8 starts to stagger. A very nasty noise/hum appeared every time I played. At this time, also the power cord, the ones that?s permanently attached to the power unit, started to come off. I had to secure it with duct tape from showing bare wire.
Ultimately, I upgraded the Gbus8 to a pedal power with isolated outputs, and now I?m hum-free!
Conclusion: the Gbus8 is ok as long as you don?t push it and don?t touch it. If you want to power high demand pedals and are on the road a lot, buy something else.
