Diago Plug Adaptors

Power virtually any pedalboard, no matter how weird or wonderful.


What do they do?

Our plug adaptors change the shape and polarity (location of positive/negative) of one output on your Powerstation or Micropower9. This allows you to power a vast number of unusual pedals from the same power supply as your regular pedals. A common example of this is the ProCo Rat, which requires a 3.5mm mini-jack (Diago Blue Adaptor) to power it.
