I'm only recently getting more into pedals and doing my first actual pedal board "build". With that said, my knowledge of this stuff is limited so I bought these thinking they would suffice in place of an actual isolated power supply, but I was wrong. I find I get a not overbearing, but still very noticeable hum/static noise when my pedal chain is connected to the amp, even with all pedals turned off. If I plug my guitar straight to the amp, the noise is gone. After doing more research I learned this is a common issue with using a daisy chain power supply. If you don't mind the noise I suppose it's fine for home practice, but probably a big no-go for recording or live use. I will be purchasing a proper power supply to replace this.
