What You Need:
-a Rock Band mic
-a 1/4" mono jack ($4 for a pack of 2 a radio shack)
-a blank or unimportant CD or DVD or a washer with a 3/8" hole and a total diameter of about 1"
-a soldering iron
Step 1: Opening the mic
Opening the microphone is the most difficult step of the entire process. You should start by cutting the cord about 1-2 inches from the base of the microphone. Then comes the hard part: Twist the top "cap" part of the microphone until the screws on the inside break and it comes free. After you do this, remove all of the internal components and discard the weight in the center of the microphone. Remove the rubber plug thingy from the bottom of the mic body.
