    Building a Mini Pedal Board with a few Pedal for home practice, and was trying to do it low cost, well do not cheap out on Power Supply's

    FYI also all those You Tube Vids Lie Lie Lie !

    Bought a used MXR Brick, have hum noisein the pedals, (Not the Iso)
    Same with a Caline CP 5 = hum noise Grrrr
    I am also getting noise from my MXR 9v power supply to, which is very strange, tried all 8 pedals individually and all were making noise DG Deluxe, Specta Comp, Mooer Pedals

    Well just bought a Iso Brick due to its size hopeully this will work or its my Voodoo 2 or I spot next

    Have you tried a one spot wall wart? I have two and have yet to notice any added noise.

    Good luck!

    Look into a Voodoo ISO5 or a CIOKS Adam5 for cheap and isolated. Dont waste your money on non-isolated power supplies. More noise, less fidelity from your FX. my .02c anyway

    I haven't experienced any issues with the Caline, even when mixing and matching Zoom multis and other pedals.

    One Spots (the actual power supplies, not the wall warts) have been the most noise free power supplies I've used. They have three different sizes now.

  6. Some places you can skimp on. Your power supply is NOT one of them. Had an Iso5 - nice piece of kit. Now have the Pedaltrain CS6 - also very nice. The Iso Brick looks cool too

    Disclaimer - running a Line 6 G50 on my board - digital wireless, yep you need isolated PS....

    I got the cheap Donner DP-1 pedal supply last Christmas and it's doing great. Powers an MXR m87, a VT Bass Deluxe, EHX Bass Big Muff, and a Snark pedal tuner. Night in and night out it does just fine. Maybe I got lucky with mine?

    Figure out which pedals require isolation and which ones don't by process of elimination, daisy chain the ones that don't and use separate power outs for those that do. That should take care of it. Nice little PS, the Iso Brick. I use it myself. Tiny and has a butt-ton of power.

    EDIT: Just in case it's already isolated, what pedal is it? Does it make noise when shut off?

    Nah, you just don't have any pedals that require isolation.

    What would exactly? I'm curious. And the Donner supply does state it's isolated DC right in the header on amazon, FWIW :)

    Any pedals that hum when on a daisy chain with another would require isolation. So far out of my stuff, the EHX Pitch Fork, the Line 6 G70 wireless, and Zoom B2 require isolation, though I never use the B2 anymore.

    Anyway, Donner stretches the truth to the point of lying. The 9v, 12v and 18v are isolated from each other, but the outputs for each voltage aren't, as they all share a common ground.

    I'm not an electronics expert, but from my experience there's a lot of misunderstanding in the forums and blogs about what makes a good power supply, and this has led me and others to sometimes buy even expensive ones only the get disappointed by noise issues. As far as I can currently understand, these are the factors:
    • Isolation from the grid
    • Isolation of outputs vs other outputs
    • Electro magnetic interference that the PS throws around itself
    • Quietness of the actual voltage supplied
    Each individual power supply will have some of these covered, and some not so much, leading to different problems on the assembled board. (E.g, I've had an isolated PS that had a transformer that induced noise into any adjacent pedal).

    For me, I ultimately settled on the MXR ISO-brick. Its wall wart is flimsy, but you can replace that, and AFAIU apart from that this unit checks all of the boxes, with a really neat compact design
