'''Electrodes''', known as '''Shock-Amplifying DevicesApmlifiers''' (増幅装置) in the Japanese version, are a kind of collar used in Underground Duelsin ''[[Yu-Gi-Oh! GX]]''. When in use, a Duelist wears three; one around the neck, and one around each arm.

==Yu-Gi-Oh! GXHistory==Electrodes were first shown when [[Zane Truesdale|Zane]] Dueled against [[Mad Dog]] in an attempt to gain more power. When a Duelist loses [[Life Points]] while wearing an electrode, a severe electric shock is sent through their body causing them great pain. After his Duel with Mad Dog, Zane used them again in a Duel against his younger brother [[Syrus Truesdale|Syrus]]. <ref>{{episode|Yu-Gi-Oh! GX|65|ref}}</ref> While in the [[Duel Monsters Spirit World|alternate dimension]], Zane used them to take [[Doom Dozer (character)|Doom Dozer]] down, before he ultimately destroyed it with "[[Cyber End Dragon (anime)|Cyber End Dragon]]".<ref>{{episode|Yu-Gi-Oh! GX|137|ref}}</ref>

When Zane was starting to have heart problems, he thought at first that it was due to continued use of the electrodes. Much later, it was revealed his "[[Cyberdark]]" Deck was the reason behind it.<ref>{{episode|Yu-Gi-Oh! GX|164|ref}}</ref>
