My DC Brick landed yesterday and I swapped it in the place of my One Spot. I used to think that the noise gate on my RP1000 was just not very good. In fact it was the One Spot causing all of the noise. If I would have used to two of them to keep some of the pedals separate then everything may have been fine but the Brick stays.
One grip, I mounted the Brick under a PT Pro and the the 18v jacks are blocked by the brackets. I guess the MXR 10 band stays on it's wall wart.
Totally depends on the rig. If I use my OneSpot with my 5150, it's dead silent. If I use it with my Mark III, it's hiss central. The Voodoo Lab PP 2+ is definitely a better product, but a OneSpot can work in certain applications.
