    I bought a Germanium OD, and I really love the sound wich can recreate The rolling Stones early hits!
    However there is a hum issue when an AC adapter is pluggesd. With a battery there is nearly no hum, but with my Zoom 9V 300mA ac adapter, it is noisy.
    What should I do? Would a 100mA or 200mA adapter solve the problem?

    Thank you very much!

    Maybe a Hum Debugger?

    The hum debugger is more for removing 60 cycle hum from single coil guitars.

    I’d recommend trying a different power supply. As far as affordable supplies go, I’d recommend the Onespot. Costs about 20 bucks and it doesn’t really have noise problems unless you use it to power analog and digital powers on the same daisy chain.

    Have you tried yourself the Germanium OD with the 1-Spot?

    Concerning the analogic/digital issue I already have other pedals: Dunlop Crybaby, Digitech Bad Monkey, The Boss TR-2 Tremolo, the Danelectro BLT.

    Do you think this configuration would work?

    Thanks

    I don’t have a Germanium OD yet, it’s on my list.

    That should be fine. The BLT could possibly not like it, but I doubt it since you’d only be running 5 pedals off of it. When you’re running 8-10 with analog and digital, then it can get a bit noisy.

    Thank you! I’ll get the 1-spot ! I had thought about the cioks Big John or the Voodoo Lab Power 2, but the 1-spot is a much cheaper solution…

    the pp2+ is awesome, I have one, worth every penny, but the onespot is nice until you get one

    PP2+ sounds like a great choice, but I’ve got a last question: Do I need so much power?
    My Germanium OD (?) Dunlop Crybaby (20mA), Digitech Bad Monkey (17mA), The Boss TR-2 Tremolo (20mA), the Danelectro BLT (?) require together between 100 and 150 mA.
    A Boss LS-2 with a daisy chain provides 200mA (-25 mA for its own consumption). It should be enough?

    It’s not that you need that much now. The previously mentioned things work perfectly fine for what you have.

    But if you’re anything like the rest of us, in a year or two you’re going to have a crap load of pedals. That’s when you want something like it.

    That’s true, it’s really hard to resist buying new pedals! But for the price , the LS-2 provide switching between two different effect loops. I guess I should buy it first, then the PP2+ when I’ll get more pedals!

    i’ve got a Germanium OD which IS noisy (either hums or makes a high-pitched whining sound) but ONLY when daisy-chained with certain other pedals…

    i’m using a good power supply (it happens with my Diago and Johnny Shredfreak equivalent – both supplying 3000ma) even if only powering 6 pedals.

    i get the hum when chained with my Sansamp pedal, and the whine when chained with my SMMw/Haz.
    incidentally, the Sansamp and Haz don’t like sharing a power supply either.

    so, i’d be slightly wary about using any power supply which doesn’t have isolated outlets. of course, the One-Spot may be fine. my Germ OD is happy enough sharing power with all of the other pedals i’ve tried it with – about 20 other pedals, both analogue and digital.

    Thank! And what about the boss LS-2 with daisy chain?

    the honest answer is: i don’t know.

    if you’re getting hum when using your Zoom power supply, then it’ll more than likely be the same if using the LS-2.
    i’m pretty sure the 9v ‘output’ on the LS-2 (and TU-2) is just a power ‘thru’.

    So with the One-Spot and the Germanium OD there was no problem?

    from what I gather there isn’t a problem, but other pedals in the chain can cause a problem
