Folks, I have been using the approach in the pic below for years. A couple of friends have asked me to build one for them as well. It's really cost effective because the "wall wart" that drives it all can be bought from a thrift store/yard sale for maybe $1-$2 (I just bought one today for $1).
Here's my question - what do you think of this as a "commercial" idea? Would anyone actually buy one if it was available? I'd estimate the over-the-web cost of a professionally built "pedal power regulator" box (including the built-in power leads to the pedals, but not including the "wall wart") to be about $40-$50 plus shipping - say 20 pounds, or 30 euro. It could power maybe 8 pedals - the one I'm using in my pedalboard today is powering 12 (supplies about 1000 milliamps).
The advantage over the usual daisy-chain approach is that it is "star" connected = much lower probability of ground-loop hum.
The advantage over the "high power switched mode" pedal power supplies that are available is that it is not switched mode... It is "linear"/low voltage and so there is almost no possibility of damaging your pedals in the event of a failure.

| I've heard sharing pedal power usually induces noise for some reason although I can't say I've experienced it. I do have one Moog pedal that is intrinsically noisy that wasn't before, but I haven't really looked into as why. |

Interesting idea, what would each lead's voltage?
Or does the pedal use only the power it needs? |

All leads are 9VDC (same as a PSA output). Each pedal takes only the milliamps it needs.

Hi Lauries2
I've been on this topcic for awhile and always have never wanted to by a power supply or daisychain. could you explain how you built it or how it works as i have a spare wall wart (9v 1000mA). How would the Power regulator thing look like and how many outputs would it have.
Thanks,
Fuzzy |

Laurie,
it probably won't be hard to undercut the current commercial devices of a similar nature as they run in the $80-300 range.
the success of such a device would vary a bit (e.g. it would sell 100x better if it included the wall wart).
the hard part is to compete with the newer daisy chain ps's such as the one spot and godlylike.
i believe the newest version of the one spot does something like 1700mA.
i have a boss RPW-7 i got used for $30, but i don't think i would have ever spent the money on a new one.

Thanks for the feedback and comments folks! I'm digesting it...

let me know if you want any help w/ business plans and margins. that kind of thing is my specialty :P
btw, as for my comments about competing with daisy chain styled power supplies, i know they are inferior, but a lot of people don't... and thus aren't necessarily willing to shell out more money for something that they feel they can get in the $30-40 range.
some of the newer wall wart styled power supplies can be purchased wholesale for like $1-2. |

What if you have a few different brands of pedals on your board or are you aiming specifically at the boss etc 9v pedal market....?? ..i.e i have a twin tube classic that takes 16v to power it and i am waiting on analog mike to come back to me on a couple of his pedals which i think run on 12v...at the moment i have a plugboard with the different adapters plugged into it and all the boss pedals and the wah powered off the boss adapter,i,ve never had any major noise probs while using the boss adapter,i tried a zoom one for a while and it really brought the older aca type pedals to life(DS-1,OD-2,CS-3 looped with psa ones to run on 9v)but it also caused a lot of feedback and a loud hum after a while in use which i could never figure out which was a pity 'cause i really thought the sound improved on the DS-1 and the OD-2 especially and for some reason i tried it on the DD-3 and even though it lit up the LED i got no sound out of the pedal.... ......... |

Pedal power - opinions about a "commercial" idea?
