All of the cheaper pedal power supplies I’ve tried so far have noise issues. This one is pro level, totally quiet. Well worth buying this. Don’t go cheap on your power supplies. I’ve had 2 cheaper units which both gave me ground loop noise. It’s got enough outputs for my pedalboard. I’m very impressed with it. The only thing I would have liked were longer cables. The cables are very short so you may want to think about buying longer cables if you have a bigger pedalboard or want to tie your cables in a tidy way. I use a pedal train Jr which I also bought from Thomann and in order for some of the cables to reach properly you would need to mount the supply right in the centre of the pedalboard and the cables will just about reach, if taking a direct straight line. I want to have my cables tidy so will need to purchase a set of longer cables in order to do this. This is not a problem and not any fault of the manufacturer. Truetone were good enough to supply mounting brackets for the unit which I feel every power supply manufacturer should do this. I advise anyone who wants to have a noise free trouble free pedalboard to get this. Don’t go cheap on your power supply get the best out there right now, get the Truetone CS7 and get it from Thomann. They will look after you as they have always done for me.
