First of all, A killswitch on a regular guitar cuts out the pickups on the guitar. Doing that causes a cool effect as heard in Jordan. Since the GH2 remotes are plastic, and don't have pick ups... The killswitch does the exact opposite. It acts as if you were strumming, but instead you are pushing a button. It may make it easier, but it still looks cooler.
This is purely for fun, and really has no point to it except to look cool.
Disclaimer: Try at your own risk, I am not responsible if you screw things up and break your remote.
This is my first Instructable, so please critic anything that is wrong...
P.S. Thanks to Weissensteinburg, I got the boxy things to work.
Step 1: What you need...
-Guitar Hero Remote
-2 pieces of Wire (about 6 inches of each)
-Drill bit that is the same size as the button
-Wire Stripper or teeth
