    So I lucked into picking one of these up at Jack's Attic Sale (Long & McQuade). It's a large effects board with many different voltage offerings and input/output options to accommodate various effects boxes, and comes with a nifty heavy-duty hardshell case. Here's the issue: I'm cabling it together, and everything works so far except my Zoom Multi stomp box. I notice that the standard 9 v dc feed on the board is 100 ma, and the Zoom box needs 500 ma. There are some other 9v options, but the board doesn't specify the amperage from them... and of course I'm afraid to blow it up. Do I keep using batteries on the Zoom or does anyone know the answer to this riddle?

    Have you checked the board manufacturer website for the product specifications?

    Apparently the manufacturer's not making them any more, so no info on the website. That was my first thought too.

    • Hardcover professional pedalboard designed to accommodate nearly any possible configuration of pedals
    • (2) 1.3 amp 9VAC jacks for powering pedals from Digitech and Line 6, etc. (2) variable DC jacks to allow any voltage from 4-12 volts (simulate an almost dead battery). (4) standard 9 VDC jacks for Boss, Electro-Harmonix, etc.
    • (1) 18 VDC jack for MXR EVH Flanger, etc. (1) 24 VDC jack for boutique and vintage pedals and (2) 9/12 VDC jacks to accommodate additional boutique and vintage pedals
    • All DC jacks have polarity switches so center negative or center positive is not a problem with the SKB-PS-55 Stagefive Professional Pedalboard
    • All DC outputs have a current rating of 100mA each
    According to the Amazon Description.

    so 2 of your outputs have 1.3 amps... just have to figure out which 2. Pretty sure its the red rectangle.....

    sorry, didn't see that without my glasses

    Zoom needs a wall wart. If they were 250Ma outputs you could buy a current doubling cable, it joins 2 outputs to 1 input but 200Ma still won't cut it.

    I have the same problem with the Digitech trio. Needs 500Ma as well IIRC so it's on a wall wart.

    I was going to suggest an AC/DC to DC buck converter placed in a Hammond 1590LB but with only 9V out there will be a voltage drop so the pedal would only be running 6.8 volts plus or minus depending on the chip used in the converter.

    Thanks for helping, everyone. I guess I need to do some more research. The board has a couple of variable dc voltage outlets (you can dial in anything from about 4 v up to 12) but doesn't specify the amperage.

    That's the one to try then. It doesn't matter if it puts out 30 amps at 9VDC, the pedal will only take what it needs, 250mA (sorry 500mA, corrected). Just don't exceed the voltage by too much.

    Thanks, Cathode Ray. I'll give it a try. Keep your tube glowing...

    Zoom Multistomp should also accept a 5V supply via the USB port.

    All the DC outputs are 100Ma. the + switch changes polarity to center positive for certain pedals that require it and the white phillips trim is for adjusting voltage. There is nothing to adjust the current.

    Please let us know the results

    I'm not so sure about that.

    or just build a cable with a 3 amp 50v diode in it
    or put in a 10 amp 50v diode bridge and a couple of caps inside the box before the 9V output jack.

    100ma is a sign that the unit uses 3-pin regulator chips to down-regulate a higher voltage for each output. Traditional 3-pin regulators come in 100ma and 1A flavours. Anything else is using a different approach or even a proprietary device.
    Because wallwarts tend to come in round numbers like 200, 300, 500, or 1000ma, manufacturers specify the next likely rating one up from what the pedal actually requires, to provide a margin of error. If the pedal truly needed 490ma, the manufacturer wouldn't take the risk of recommending a 500ma unit but would have said 750ma or something like that. Nothing would "blow up" in the pedal, but pushing any electrical device to its limits results in heat being generated and compromises the lifespan of the heated device. So the odds are quite good that the Zoom units needs much less than 500ma, but more than 200ma, such that a 500ma recommendation meets all the safety margin needed.
