Velcro base to attach pedals, in/outs to run to front of amp with option to run a second loop through your amp's FX Loop. Has its own power distribution. At one point I think I had to replace or repair the 9v jack. I don't have a power supply but any pedal supply will work. It does still have an assortment of jacks to run from its power jacks to each pedal. Served me well once upon a time.
