Reddit reviews Donner DP-1 Guitar Pedal Power Supply 10 Isolated DC Output for 9V/12V/18V Effect Pedal

I went with this one. Lots of favorable reviews.

I was using 2 One Spots and just wasn't happy with it. This takes care of most of my board and I have a One Spot powering 4 pedals. Love that this has an 18 Volt option.

My Philospher's Tone was really noisy when engaged with the original plug. It's much quieter plugged into this thing. I'm surprised, but thrilled with the results.

it already exist

You have to be very careful with this route as guitar pedals use reverse polirity for their power. Rewiring the cables is a must.

I don’t have experience with the more expensive brand true isolated power supplies from brands like Voodoo Labs, T.Rex, Etc. But a lot of the people I’ve talk to and jammed with do and they seem to work just fine.

Strymon, TrueTone, MXR, and Walrus Audio also make them.

I have an inexpensive Donner DP-1 which isn’t truly isolated but it’s stable, cost effective and noise free in my setup. It’s also generally well reviewed.

It’s got seven 9v 100ma outs, a 12v out, and an 18v out all at 100ma, and one 9v 500ma out. And I’ve been using it with a few different analog pedals for about a year I think.

Is there anything you need specifically that you can’t find?

These are not isolated, as you can see in the reviews. You can get them a lot cheaper as well.

(Same device, just different brand. Probably made in the same factory.)

I don't personally, but those are good power supplies. The Voodoo Labs supplies are popular as well. I actually run two cheap power supplies I got on Amazon - they aren't completely isolated, but I have had 0 issues with them at all: Donner Dp-1 Guitar Pedal Power Supply 10 Isolated DC Output for 9V/12V/18V Effect Pedal https://www.amazon.com/dp/B00WHLLDWO/ref=cm_sw_r_cp_apa_e4Ozzb3PHSFDH

Yeah, all of the Chinese PSU's aren't isolated but claim to be

it's just a daisy chain. this has been documented, check the product questions/reviews, google it as well-forum posts

I have this already https://www.amazon.com/Donner-Guitar-Supply-Isolated-Output/dp/B00WHLLDWO/ref=sr_1_1?ie=UTF8&qid=1495833819&sr=8-1-spons&keywords=donner+power+supply&psc=1 which is about the same thing.

I just don't like that the best way to connect it is a flimsy and cumbersome wall wort. I'd much rather have a hefty and universal extension cable.

1x4 board cut to desired length, built into desired size/shape. $5-20, or possibly repurposed.
Stain, sandpaper, glue, miter box and saw, clamps. $50 mostly reusable, building tool kit.

pedalboard tape $30 enough for 10-15 pedalboards.

isolated power supply $40.

The tape is the best, I unabashedly recommend it, 3M makes good stuff. The power supply I cannot recommend for or against because I have no experience with it. I'm sure some time shopping and researching will find a $40-90 solution that is recommended.

I'd suggest making the top at least two boards 18-24" wide with a 1" gap between them. Connect them with three angled bits to a bottom piece made from two more boards. Leave room for the power supply between top and bottom. Use the gap between the boards to keep the wiring. You can use more board to build a cover. Cabinet hardware to secure top to board, but be removable. It can look as raw or polished as you want. Paint, stain, stickers, whatever.

Edit: Also, watch That Pedal Show. Depending on your time, the above materials plus the time to learn and redo mistakes can quickly add up to "It might be cheaper to buy a manufactured board".

Non isolated: https://www.amazon.com/Donner-Guitar-Supply-Isolated-Output/dp/B00WHLLDWO

That listing says it's isolated but I am almost certain it's not, but for 40$ you get 8 9v outputs + a 12v and 18v. 1 9v is 500ma so you could daisy chain it for another 5 100ma pedals.

Isolated:

The Donner ISO 8 cost 80-90$ but is actually isolated though it only has 8 outputs but a few are switchable from 9-12-18v, and it has 2 300ma outputs so once again you could chain up a few extra pedals.

I have the cheaper supply except it's branded as Caline, otherwise it's identical. It's worked great for a long time, even though it isn't isolated I've only had a few pedals that were noisy with it. The only downside is a lack of on/off switch, but I just unplug the power input which only takes a few seconds longer.

I know you said you don't need higher voltage outputs, but they can be nice. Eventually you may have a use for them, some pedals really do sound better at higher voltages though only a few are made for it. Also the Donner ISO 8 has 2 4-9v outputs so you can starve pedals which is an interesting feature.

I have a big Pedaltrain board - I think it's like 32 inches long. I recently decided I needed a smaller board for when space is tight, or when I don't want to lug 50 lbs of pedals. I went with this board from Gator. I also have a Voodoo Labs power supply on the big board, but I was feeling poor when it came to the new one. I wound up going with this one, figuring I could always return it, if it was noisy. But it's been dead quiet and powers the pedals fine.

$40. It’s a workhorse, had it for years with no issues. Here’s the link

Alternatively, here's a non-isolated brick for slightly more, but will look much much nicer on your board

Edit: forgot the link. http://www.amazon.com/gp/aw/d/B00WHLLDWO/ref=mp_s_a_1_1?qid=1449974688&sr=8-1&pi=SY200_QL40&keywords=isolated+power+supply&dpPl=1&dpID=51TjSpRlIEL&ref=plSrch

I use this one which seems fine. And the humming seems to be only coming from the fuzz pedal.

Sorry, misread the question. It has individual current ratings depending on which output you plug into. https://www.amazon.com/gp/product/B00WHLLDWO/ref=oh_aui_search_detailpage?ie=UTF8&psc=1

If all of you guys are wanting a power supply thats not stupid expensive https://www.amazon.com/gp/aw/d/B00WHLLDWO?psc=1&ref=ppx_pop_mob_b_asin_title

Check it out, currently running it on my set up, even my strats are quiet.

Price wise well it beats buying a voodoo lab power brick promising the same performance.

Cheers too all, and nice set of drives mr OP

Behringer makes a version, although I doubt it's much better quality, if at all. I've had my 1Spot for years and it's never failed! It's possible you had a dud. I'd give 'em another chance!

Another option would be to get an inexpensive power supply to leave at home. I have this one on my board. It's basically a glorified daisy chain but with more voltage options. I really want a fancy isolated supply but couldn't justify the cost at the moment. This one one suits me fine for now and I could see it doing well in a at-home convenience situation.

Thanks for the tips! I am powering everything other than the digitech pedals with a Donner power supply (https://www.amazon.com/Donner-Guitar-Supply-Isolated-Output/dp/B00WHLLDWO).

I will try putting the NS-2 after it.

Donner DP-1 from the looks of it.

I have to disagree somewhat.. in my experience the daisy chain 1Spot was really noisy and would squeal when attached to certain pedals, in addition to adding noise to the signal. I now use a cheap Donner supply which isn't isolated, but it is a big step up from the daisy chain, for not much more money.

/u/fishfryy if you can afford it, get the proper isolated ones mentioned above, that's what I'm doing next. If you need more power, then the 1Spot C12 (not a daisy chain) or Walrus Phoenix are both good options as well.

I’m looking at buying a pedal board and amp for my acoustic guitar. The amp is strictly for home practice and not for gigs. For the pedal board I was looking at the gator aluminum board: https://www.amazon.com/dp/B00IJYE1CW/ref=cm_sw_r_cp_api_i_q9j3Cb8P04M3V
For the power supply for the board I was looking at the Donner DP-1: https://www.amazon.com/dp/B00WHLLDWO/ref=cm_sw_r_cp_api_i_j.j3Cb1VH1V0Q
For the amp I was considering the Acoustic A20. I was just interested in any feedback and recommendations?

If you are planning on getting any other pedals, consider getting a multi-supply power box, like this.

They're pretty cheap and handy.

What you're looking for is called a "boost converter" in power electronic terms. If you find one, make sure it has good filtering since it's going to have a switch in it that creates noise unless it's an expensive or heavy linear converter (usually with a transformer in it).

If I was going to do this, I'd either just deal with two supplies or get something that kicks out all of the necessary voltages like this:

https://www.amazon.com/Donner-Guitar-Supply-Isolated-Output/dp/B00WHLLDWO

The problem with the multiple output voltages is that the receptacles on it look like they are the same configuration, so you could accidentally plug your 9V pedal into the 12V or 18V ones, and that could cause catastrophic damage.

Because I'm kind of an idiot, I don't like using systems/connection configurations that combine voltages unless I really need to. If I end up plugging the wrong thing into the wrong thing, things blow up. I'd just keep a separate wiring system for things with different voltages even though it's annoying so I didn't do anything stupid.

I have one of these https://www.amazon.com/dp/B00WHLLDWO?psc=1. I've only had it around 6 months, but it's been reliable and is reasonably priced. It's got 8 9v, 1 12v and 1 18v outlets. 1 of the 9v is 500ma so if you don't have any high power draw pedals you can put a daisy chain cable off it to power more than one pedal. All the other 9v are 100ma.

depending on your budget

low (~35 bucks): one spot, donner dp

medium (~90 bucks): donner iso, mxr iso brick

a bit higher (~120 bucks and up): truetone cs7, voodoo labs pp2, walrus aetos

all these should cover your current and future needs. the medium and higher priced ones are isolated and will have clean power, the one spot and cheaper donner might introduce some noise depending on what you're plugging in to

I have one of these- works perfect. https://www.amazon.com/Donner-Guitar-Supply-Isolated-Output/dp/B00WHLLDWO/ref=sr_1_1_sspa?hvadid=77653013976887&hvbmt=be&hvdev=c&hvqmt=e&keywords=donner+pedal+power+supply&qid=1563761923&s=gateway&sr=8-1-spons&psc=1

Anything isolated in my opinion. You could do a 1 spot in the meantime, but I stopped using mine several years ago after I got more pedals. I have a Walrus Phoenix, but that’s totally overkill for you right now. They have a smaller version called the Aetos which is really great. It’s on the higher end of the price. MXR and T Rex have some options that are around the $99 mark. Amazon has some generic versions called Donners, which I’ve seen before and will probably work fine for a while. I guess you just take the risk as it gets older of the probably no-name transformers going out and surging your pedals; maybe not worth it then.

I do highly recommend either the MXR mini and T Rex mini are my most recommended if you can afford them.
