It's easy to make, you can make one yourself.
The results are quite electrifying. If power is what you are looking for, this will get you there instantly!
Simply take an electric chord that plugs in the wall, cut the wires and strip them, then do the same thing with a guitar cable, then take all the stripped wires and twist them together, then plug in and play! It's AWESOME!
I'm so sure you'll be happy with the results, thst I'd like everyone to share in your joy, so if you decide to do this, please take videos and post them here so everyone can enjoy it with you!
I'll go make the popcorn....
