  • Can you better describe the #10 guitar string in electrical terms? Like is it just a steel wire? If so, what is the diameter? I would assume that if I put 24 VAC across any steel wire, it would pull all the current the transformer could provide, and lower the operating voltage well below 24 volts, and pull more than 2 amps, ruining the transformer in short order.

  • @MIRCWOOD How you hook it up? I mean the negative and positve from the jumpstarter to the string.

  • Great video!

    How warm does the string get? And do you get a full 12V - 2amp shock if you accidently touch the string?

  • MrJaklein using a guitar string worked great for me, thank you for this video. I just cut the nose off of my redbull edge 540 foamplane using a guitarstring, after seeing your video. I just used a portable jumpstarter and it cut like a worm knife through butter and it made a very clean cut so thanks again : )

  • @F0RD0Z

  • wow! now i can burn , cut and elecrtify myself at the same time!!!!

  • you use 24volts with 2 amps

    is 12 volts with 1,5 amps also good??
