Invaluable pedal, one of my favorites. I have multiple so I'm just selling one off as I don't feel like I need a backup. This works great with no issues, can be powered off the red cable from a pedal power plus 2.

These all introduce a bit of noise. ALL of them. Power supply does not make it better. It's mainly noticable with a low output signals, it can be made much better by putting some kind of gain boost in front of it to just make your signal louder. Just being up front with this as I found it to be an issue at first.
