Our manufacturer made this batch with standard polarity: The barrel is negative polarity, and the pin is positive. This means they are . . . not for pedals!
We figured it would be a shame to just throw these out, so we're selling them cheap in the hopes that you creative people can use them for something. There's enough e-waste in the world and we'd like to not add to it.
Once these are gone we won't be carrying them again.
Beginners: These USB to 9V power cables have standard polarity -- AKA the barrel is negative and the pin is positive. In the pedal world the barrel is positive. If you are looking for a USB to 9VDC cable to use with your pedals, click here.
