I have a DC Brick powering one pedal board and I also have a VooDoo Labs power supply I have never put into service.
What brings me to my question is a silly situation of needing 90° plugs for one section of a pedal board where spacing front to rear is tight.
As I start looking into daisy chain extensions w/90° end plugs I find there are wall-wart power sources providing up to 1A or 2A of power being sold with daisy chain extensions.
For the most part, if I can get 1000mA or 2000mA from a simple wall-wart and daisy chain, I wonder why I would want/need the more elaborate power sources. I realize many pedals use as little as 10mA to 15mA and some others may use much, much more, but 2000mA is quite a bit of power when it comes to guitar pedals. I also realize there can be the 18v requirement of some pedals as well.
Looking for some useful clarity here.

It really comes down to what you plug the wall wart into. My stage rigs all have power conditioners, and they filter out the ripple, etc., so they provide a constant sin wave voltage. They also alert me to an open neutral or no ground. There's also a line voltage display and you'd be amazed at how much variance there is in voltage from venue to venue. I've seen high 90's to 125V readings, A lot of the cheap wall warts have no voltage regulators in them and usually no filters, so without a power conditioner it's a crapshoot what you're putting into your pedals. Then, there's the age-old problem of you get it dialed in during sound check and then the house lights go off, stage lighting comes on and everything changes again, so yeah, no way I'm gigging without a power conditioner. With good smooth power your pedals will usually not get "saggy" like they do on batteries.
Good battery power supplies are usually voltage regulated - but- lithium batteries are EXPENSIVE and require constant maintenance to dischage them to storage voltage between shows, then charge for the show, then discharge, on and on or they won't last and that's way too much work. Plus you get all the expense and farting around with the smart charger.
Everyone's needs vary, but for for me playing on different stages all the time the best solution I've found is a power conditioner and filtered power supply.
BTW, your amp will thank you for the smooth power too.

I’ve used the Truetone 1-Spot for years and never had any problems with it. I have a couple pedalboards where I’ve daisy chained 9 volt pedals with the 1-Spot with no problems. It does look a bit crazy though with the little cord going out to a power strip where the wall wart sits. It’s supposed to be “triple filtered” but there are some reviews of weird oscillation sounds coming from certain pedals such as the Engl Cab Loader. I’ve never had such problems with my pedals. My current rig (Voodoo Lab Dingbat pedalboard) has a built-in brick power supply but it doesn’t have an 18 volt output for my Mini Dejavibe. So I run its wallwart PS separately. truetone.com/1-spot/ |

Different power supplys also make your rig sound different |

Sounds like the answer is to try at my own risk on the 1A or 2A wall-wart daisy chain. Good thing is they are fairly inexpensive. One thing I like about the thing is it being very convenient in that there is no box to deal with. I wouldn’t be using it anyplace other than my music room, so it it works well enough there I have no other environment to be concerned with. I see some indicating a "magnetic loop” which is intended to suppress noise.  s-l960 by Larry Madsen, on Flickr |

I'll need you to explain the question.
Are you referring to my comments or the "magnetic loop"?

I have no idea other than what the marketing info says. I am far from an electronics expert; I mentioned it as a way of possibly gaining some input from those much smarter than myself  I did go ahead and purchase the item though ... actually one like it. It's cheap. Maybe too cheap to be any good.  www.ebay.com/itm/204394065040This is my problem: I built this smallish pedal board. I provided no compartment for a brick type power source, hey it was built to be smallish. In building it smallish I created a "semi" mistake and made the upper deck to narrow to accommodate even jack plugs unless they are very short.  Small Pedal Board by Larry Madsen, on Flickr If this power source works out for me, it is perfect for what I need. I can see now that I need to add an extra maybe 1/2" to the front overhang on the upper deck. It won't impact the lower-level usage and it will provide some relief up top. I have the wood and the carpet on hand. It's an easy modification. |

The thingy on the cord you're asking about is called a "ferrite" or sometimes a "bead" or even a "ferrite bead." Very common in wires that carry signals, You can look them up on the Google. In short layman's terms, it acts like an inductor for low frequencies and like a resistor for higher frequencies. It can filter out noise in the power line.

Thanks for the info chuckmi. Hopefully the power supply works out well in my room.  |

Yes, passing the DC power supply wire through the ferromagnetic ferrite core should significantly increase the wire’s inductance, thereby helping to impede the passage / filter out any high frequency switching noise from a switching power supply. ie most modern compact lightweight power supplies.

My first thought when I constructed this board was to power a few pedals off my TU-2 tuner. I could easily exceed that capacity.
This power source should handle the electrical load. And I could still power a pedal or two from the TU-2, if I power the TU-2 from a separate source.

Chuck will it get rid of buzzing and can i buy one that goes in line with the 1 spot true tone wall wart thks That depends on the source of the buzzing. If it's coming from your power supply then - maybe. If it's coming from RF that the guitar is picking up then, no. The biggest issue we run into is stage lighting. In larger venues the power to the lights is often still DC for dimming and the rectifying power supplies used for them are notoriously bad when it comes to hum. Even worse are the AC lights that have older mechanical dimmers. That's why even though there is sufficient power available at the venue the band and sound will commonly run on generators. That's also why you'll see big fans at outside venues. The "shell" type of venues are really, really bad about trapping in diesel fumes from the gnerators. I've been pretty sick onstage because of generator fumes a few times. But the show must go on. Chuck |

I suspect he has a different problem and will need a dummy coil under his pickguard.
If you turn the guitar and the buzz changes it's most likely not the power supply.

Well, It arrived.  IMG_5905 by Larry Madsen, on Flickr I guess I'll go toss some pedals on that pedal board and see how it does. Here we are, 4 rather random pedals hooked up. Not hearing a bit of noise until I turn on the "King of Britains" pedal with the overdrive. It's basically a "plexi" pedal. I think that noise is a result of the OD of the pedal itself ... not the power source.  IMG_5906 by Larry Madsen, on Flickr |

That pedal you hear it because of the gain. Looks like you have it cranked up there pretty high. This reads like it's home/hobby use. Do you have any LED lighting or dimmer switches in your house? If so, try turning them off and see if the buzz is still there.
Additionally, it's more common to put the time-based effects after the gain stages in your signal chain. Try moving the chorus to after the gain pedal. And having a chorus AND a phasor? Wow, that must be pretty swirley. Cranked gain and a phasor, let's play some 80's rock! I can dig it!

Yes, my room is pure home/hobby use.
I do have a house full of LED lighting. 8 LED overhead recessed LED lights in the room, no dimmers in the house at all.
As mentioned, these were just random pedals I grabbed to get it hooked up, no real sense to it.
I did do some various settings on the Britain's pedal and of course lower (or no) gain cuts the noise.
I can give it a test with lights out and see if there is any difference.

i have noticed on mine that it buzzes more the more i turn the amp up even without guitar. volume 4 its quite volume 7 its noisy and i usualy run my ampsy up at 7 or higher

Got the board situated. Extended the overhang on the upper level. Also made provisions for the daisy chain to reach through as needed for clean pedal installation on the board.  Pedal Board Daisy Chain Power by Larry Madsen, on Flickr Below is the board now with the same pedals sitting on it as was in post #8 Things fit much better, and the plugs can fit inside the case even with the lid on.

i think im going to break down and buy some of the Ferrite core filters but dont need 60 only need one. How can i figure out what size to get for my true tone one spot power supply thanks |

A real long shot: I bought a regular power supply a couple of weeks ago (basically, looks like yours). It came with a ferrite core attached to the output cord, and that ferrite core is located about 6 inches from the plug (and not at the power supply end).
