The supply I got was broken from the get go.. Well, it turned on and powered my pedals BUT there was this horrific super high pitched noise that the brick itself was making as soon as I plugged the thing into my wall.. It was like the coil whine you get with some super cheap and bad power bricks. Not really noticeable when playing, but pretty irritating in a quiet room.
Sending it back as soon as possible, and switching to a different brand of supplies.. No more Truetones for me.
