Fast delivery and easy to use,



Great adapter.


Another product I bought didn't have a power adapter included. So I had to buy this so as to not be solely battery reliant. Other than that situational gripe, it works great.




This adds to a solo act


It adds fullness, variety and sweeeet to a solo act especially. sometimes I find it hard to get backup singers for harmony, but this helps. You don't want to overdue it, because you could wear out the sound, just pick where it adds the most. It's a challenge to get just the right mix of harmony, volume and how to project your voice to get just the right blend, but it can really add to the sound....you can even use it at Halloween to freak your friends by harmonizing your speaking voice...makes your voice sound demonic...

Great Product


If you have boss pedals, then you already own one and know it is a necessity. I've wasted money on countless other universal power adapters and not only do they burn out, they also interfere with my sound(buzzing feedback in background). Just save yourself the money and get this unit because it is built with quality and the musician in mind( only takes up one plug and doesn't block others) unlike cheaper units and it also works with the 1-spot daisy chain cable so you can power up to five pedals.
