Listing is for one of my TGI Powerbox guitar pedal multi power supplies. I used this and another one to power my pedal board. It has 6 9v outputs, 2 12v and one 18v. Comes with the powerblock, power pack, 7 boss style cables, a daisy chain style to power multiple from one output and a red boss style one that I never used which I believe is the inverse polarity cable. Has velcro on one side as it was stuck to the underside of my pedal board. I have 2 of these for sale so checkout my other items to see the other one if it's still available.
