We have had several customers come to us with a little black box power supply that has a dragon in gold on it and you can not find jacks to fit the plug ins and some have not run at all. Please take a good look at your power supply when you buy it to make sure 1) the footswitch has a plug in or is made in combo with the clip cord and 2) you really need a good 10 wrap coil machine, they will line or shade according to how you set your machine ..a 8 wrap tends to heat up and a 12 wrap is alittle overkill , but better over than under. We are seeing more and more of this problem so please make sure you deal with a local company so if you have a problem they can fix it. thanks for looking.
