Guitar Hero Pedal Conversion

So i was sitting at home and playing my electric drums and i was thinking, can you connect the bass pedal to the guitar hero drum set? i found a plug and then i made this instructable. so please enjoy it. My first instructable!

Step 1: Gathering Materials

So first you need to get a pedal from a old drum set, preferably with pressure pad or else this wont work.
Then you need a 2.5 mm double male cable, then you need one of those 2.5mm to a 9.mm plug and that's all you need! (you need a GH drum set)

Step 2: Assembly of 9.mm Cable

Ok so take your 2.5mm double male cable and add the 2.5mm-9mm plug to one of the 2.5mm ends

Step 3: Plugging It In

Plug the 9mm side of the cable into the pad and then the 2.5 into the drum kit and then you're ready to go!
