Needed to ISO power my TimeLine, Drop, EHX HOG and MIDI controller. Unfortunately was getting too much ground noise with this brick. Probably not isolated well, just 300mA outlets apart from 5mA. Changing the pedal "order" in power brick has huge impact on hum and buzz levels. Generaly, I was getting less noise in last two outlets (500mA). Probably noise from input transformer. Some combinations within 300mA, outlets was noisy as hell. The Brick gets quite hot in 20 minutes (40-45*C). Returned the unit.
