    After seeing the thread here on the Ammoon Stereo Looper, I decided I needed one of these so I got one off eBay for $61 shipped from overseas. (found out you can buy them on Amazon but for $30 more than I paid)
    Well, waited two weeks for mine to come in from China and it was dead as a door nail. :mad::frown:
    Let's see if there's any customer service worth writing home about...

    But I will post my experience here.

    OK, stupid question here. From the Ammoon site, it says this about the 9 volt DC power supply required:
    "Please use the DC 9V 140mA power adapter whose polarity is positive pole outside and negative pole inside."
    I had two 9 volt chargers on hand but the outside was ground and the inside hole was 9 volts positive.
    I just ordered a new one (D'Addario) from Amazon and it states that the tip is negative and the sleeve is positive.
    So were the adapters I used reversed from this? I'm a bit unsure but it seems like the "sleeve" is the outside and it doesn't really have a tip but a hole.

    Needless to say, I'll feel a bit sheepish if the new power supply fixes the issue. I suppose I could fix up a 9 volt battery to it just to see, but the Amazon order is supposed to be here tomorrow.

    I just noticed on the box that the importer is "Fishing King". Hope this wasn't in the same container as a bunch of frozen Tilapia. :shock:

    Yeah, pedals are generally center negative. Boss created the standard ages ago - partly to keep people from just using power supplies from old phones or something, but probably more so to sell their own supplies.

    I should mention that my last experience buying a D'Addario / Planet Waves adapter from Amazon wasn't what you'd call positive either.
    I got some UpBright adapter in a manilla envelope with a hand cut taped on label. Mine is the second review. I've had good luck with their Dunlop supplies and the house brand supplies from Monoprice.com.

    I also keep a handful of these around

    I usually have to flip the polarity (cut the wires, flip them and splice) but that's trivial.

    I also keep one of these in my bag when I go to lessons for my pedal tuner.

    I rewired it at the switch. Works fine.

    Let's say it's a "female tip" ... :shock: But you did write that they say positive pole outside and negative pole inside.

    Hope there's some kind of overload protection in the pedal and you didn't just fry it.

    Most likely there's a diode that'll prevent the polarity snafu from causing an issue.

    I tried it with the correct polarity DC supply and nothing. In my enthusiasm to use it when I first got it, I didn't check polarity as I assumed that the center hole was positive since it makes sense to shield the hot and have a larger, exposed ground. WRONG! So no matter what or how, it's dead and it's never shown any signs of life... or death.

    Is it cute ? Could it make a nice necklace for your girlfriend or something ? Belt buckle ? Door stopper ?

    I hope you will figure it out or get it replaced as I am enjoying mine!

    Assumptions about what makes sense vs the reality have caused more then their fair share of damage.

    Did you get a REAL D'Addario supply or one of the knockoffs?

    Looks real. It wasn't in a plain white box but one labeled Di'addrio. It does say Made in China.

    Sounds like they're selling the real ones again.
