Heavy-duty power supply

[dlenaghan]

Hi all -

I've been trying to come up with a good solution to power supply problems with pedals that pull a lot of juice. I've got a nice regulated supply for my 9v pedals, but I've got an EHX Hog and Moogerfooger to think about on top of it.

I've tried the OneSpot, but I get some nasty whine when they're both plugged in, though the OneSpot seems to deliver the necessary amperage. They're both 9v pedals, but they seem to exceed the power supplied by isolated supplies, which might get rid of the whine they get when used off the same supply.

My Artec power brick supplies 6 channels of 9v 200mA, pretty standard, plus two other channels that are adjustable from 9-12v, not sure of the amperage.

I had hoped the Dunlop or Voodoo power bricks might have something better, or the Fuel Tank, but it looks like they're all similar numbers of channels, as well as limits on amperage although it's nice to see they've got bridging for higher voltage pedals.

The advantage of the OneSpot was its ability to deliver 'noiseless' power up to something like 1900 mA, which is right around what the Hog (500mA, though whether that's totally accurate or not is beyond me) and the 'Fooger (around 1200mA) come to.

Anyway, I really need to avoid wall warts (and I really don't want to have to pack a power strip on top of it all...), and my pedal board is heavy enough packed with the more standards pedals and the Artec brick.

Any suggestions? Is it unreasonable for me to think there's a slim and portable (OneSpot) but genuinely isolated/regulated (Dunlop/Voodoo/etc) solution?

Bah. Humbug. (Found the Juice Box. 300 bucks though..)

The Dunlop is a fake, it cosmetically looks like the isolated bricks but it's just a daisy chain.

As far as getting isolated outlets in a super-compact form, yes that is unrealistic. It takes either a transformer or a little circuitboard for each individual isolated output, which is why when you group 9 of them together it only makes sense to house them in a brick-shaped box.

Godlyke has an adapter gadget that isolates any one individual outlet off a daisy chain, but it fails on several levels: adapter is bulky, so if you need more than one you lose any space-savings; it only allows a modest amount of current draw, not enough for digi or tube pedals that are likely to benefit from isolation; and the adapter requires batteries, when the whole point of a plug-in supply is to not use batteries.

Yeah, I think the Juicebox is the contender. Group like pedals in the 8 outlets (4x2 isolated supplies), then use the bigger mA effects with odd polarity ('fooger) in the 9 and 10 spots.

Daisy chain any add'l small draw pedals from one of the 4x2 groups.

As the guys in Jaws might've said in this situation: we're gonna need a bigger board.

My tendency lately is to use a Onespot or Powerall for five or six pedals that have no noise/hum problems sharing a common ground, plus one or two individual wall warts for the pedals that need those. If I had more pedals that needed isolated outs I'd get the Voodoo Iso-5, again using it in conjunction with other supplies as needed.

What about the Gig Rig Generator:

TheGigRig.com Generator

Loads of power, expandable, and the adaptors for varying voltages, isolation, etc don't look too big.

I don't have any experience with it, but it's been on my radar.

That looks rad as can be. Further research warranted!
