Just so you know, this is my first Instructable, so if its really messed up, sorry. Also, my images were taken on my ipod so they might look sideways.
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 knife
-sharp scissors
-a soldering iron
-super glue

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.

Step 2: Soldering the jack

Note: My soldering iron conveniently broke, so I just twisted on the wires, but you should solder it.
Splice the black wire coming from the microphone part about 1 inch from the end. Inside there is a white wire (the lead) wrapped with bare copper wire (the ground). Twist together all of the ground wires. Splice the lead about 1/4" to 1/2" from the end and twist together all of the lead the wires. Solder the lead wire to the tip part of the jack. Solder the ground to the ring part of the jack. After you've finished soldering, plug it into a guitar amp or pa and make sure it works.

How well does the mic hold together after you broke the top off. I really want to get inside to replace the dynamic mic component with a higher quality condenser, but I was hoping to keep the USB pre amp and board, along with the current casing. Did you just glue it back together, or did it all just kind of pop back in place?

Hi, what would you say the quality level of this converted microphone is? Due to the mics limited reach i wanted to do the opposite, add an xlr connector to where the mic goes on the circuit board so it can be hooked up to a better quality mic and still be able to use the built in usb sound interface.

Hi, sorry I didn't reply sooner, I was away from home for a while. The mic itself isn't spectacular but I used it to record an acoustic guitar and it sounded fine. I used the USB interface soldered directly to a 1/4" mono plug to record electric guitar and bass and it sounds great. I'm almost positive you would be able to use an xlr connector and a good mic.
