    Does the trick, finally!
    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!

    PROS: Better pedal tone & boost.

    Good price.

    CONS: None

    Works with all my 18v pedals
    I've used this with three 18v pedals -- Fulltone OCD, MXR stereo chorus, and MXR EVH Flanger. No troubles. The OCD really benefits from the extra power!

    Free advice: I took a silver Sharpie and wrote 18v on the top so I know at a glance not to use this with the wrong pedals.

    No complaints. Woks as it should. Makes electricity.

    Best Option Around
    These things, for some reason, are pretty pricey everywhere else. Thank goodness for monoprice. It works great for any / all of my pedals that require 18v for proper operation.

    Great product. I fully back it.
    If I weren't a broke musician, I would have just stock piled these. Works great. Though I've only had it for a month, I would expect it to last, based on the other mono price gear I've purchased.

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

    Response from Monoprice
    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!
