D'Addario Accessories PW-CT-9V DC Power Adapter – Pedalboard Supply - For Pedal Board and Other Devices Requiring 9V – 800mA Max Current

I am a pedal junkie and adding just one more pedal needed a long cable length. The size of the plug fit under my board, easy to install, no noise, I'm happy and D'Addario is an excellent brand. And, the price was right. Win-win.

I thought I was going to have to replace the power port on my Casio keyboard. I tried four different power cords. One of the power cords worked, so long as I moved it around a bit and held it in place. The other three did not work at all.I know that none of the cords were faulty, because I tested 2 of them myself and the other two were brand newOne would think that I would have stopped after trying four power cords, but not me.
