    I received a defective power cord. Perhaps it was just one bad example, but it didn't work from day one.

    Hello Jamie,

    Thank you for your review on PID 611691! I truly apologize for the inconvenient experience you have had with this power supply. If I may ask, what device did you try using this supply with? If possible, can we test it with other pedals to see if the issue persists? What about with a different outlet?

    Please let me know you results. If the power supply still fails to work, I can assist you in setting up an RMA for a replacement as we cover this product with a one year warranty. Also, obtaining the replacement would be of no additional cost to you. Sorry again for the trouble and I hope this helps!

    Pros: Better pedal tone & boost.
    Good price.

    Cons: None

    After ordering two 18volt power supplies on ebay that did not work, I was super excited when Monoprice started to offer this product. It worked right out of the box for my Fulltone OCD and Fulldrive pedals. It definitely adds some fullness to the boost and smooths out the distortion a bit, in a really nice way. If you have an overdrive pedal that can handle 18v, I definitely recommend giving this a shot!
