Nothing too complicated going on if you look at the back and compared that to the front
There's Neutral and Hot and ground
Instead of the hot being a direct contact front to back, it is routed through a fuse first and then out the back
There is nothing hard about it at all. I purchased it to simplify the building of the amp I am working on which it will certainly do. I am in the middle of trying to layout a sluckey inspired plexi/800 amp with two tone stacks, overdrive and inboard active effect circuitry. I probably could have figured out what I had done wrong myself but I was at a point where I couldn't see the forest for the trees and needed and asked for a little help which forum members kindly provided.
I am also trying to confirm my understanding of your relay power supply in a relay circuit and determining which jack to use with a single button footswitch fed through a two conductor wire and whether I have wired the circuit correctly. I have used the Dumble 12 volt relay power supply in the past and yours is much easier and less time consuming to use.
I will attach the layout I drew in case you have a minute where you can review it to see if it is correct? I know it has been talked about on the forum but not with the pictures I need to comprehend it.
Thanks
Mike
