    Works perfectly. However, if you think you are attaching this to your daisy chain think again. This will not work attached to a daisy chain, it needs its own dedicated power supply/1 Spot.

    The advice from the GC rep didn't pan out.

    I bought this for use with my Eventide H9, so I could simplify the power source for my 5 pedals on my board with the One-Spot. While it may be reverse in polarity from the Boss style connectors that come with the One-Spot, it doesn't fit the Eventide H9.

    This is very handy for my digitech whammy pedal because it allows me to use only one spot in my power strip instead of the whomping two that the power supply that came in the box with the whammy uses note do not use this in one of the links that 1 spot sells because it drains a lot of power but that just might be the whammy pedal.

    Hi there - Have a big box fulltone 69. Is this the piece I need to add to my one spot to power it? Thanks!
