I have been spending a lot of time building pedal boards lately. I built a guitar pedal board and a bass pedal board for myself, and I helped a friend build two guitar pedal boards (one for the road and one for his studio.)
I've tried a couple of cheap, no-name, centralized power supplies before when building pedal boards and the results have not been good.
I decided for all my future boards I would rely on Strymon Zuma and Ojai power supplies because when it comes to power, I want the best.
Here are some of the key features of the Zuma.
* 9 high-current, fully isolated outputs
* 9 outputs offer 9V DC option
* 12V option provides 375mA, 18V provides 250mA
* Fits under most pedalboards
* Expandable by adding Strymon Ojai accessory
* Designed and built in the USA
I have tested this power supply by running dirty power into it, clean power into it, and power from an old outlet, connected via a 50-foot, extension chord. No matter what I tossed in front of the Zuma by way of a roadblock, it performed like a champ.
What you want is super, clean, unadulterated tone, unmolested by the power supply and with Zuma that is what you get. It's the highest horsepower, most technologically advanced effects pedal power supply of its kind.
Why is it so clean? Well in addition to being very well built, each of the power outputs has its own dedicated regulator and custom transformer.
Zuma also offers dual-stage topology, pre-regulated outputs, optically isolated feedback, and advanced multistage filtering. And don't forget the dual isolation. Zuma’s all analog circuitry offers two stages of isolation, completely eliminating ground loop and AC line noise issues
You can add more outputs by connecting a Strymon Ojai (sold separately) with the 24V Out jack and cable that is provided. All of the power cables you will need ship with the unit.
If you want a power supply that is quiet, doesn't bleed over into your signal chain, and that is safe, steady and reliable, I highly recommend the Zuma.
The bad news is that it isn't cheap. And Strymon NEVER discount their products. You'll pay full freight - which is $249. I think it's a bargain because you could easily lose that much money with cheap or out-of-whack power supply that blows up your pedals.
