Introduction: Guitar Hero Controller Mods

Add a "killswitch" and a jack for future projects onto your Guitar Hero controller.

I've been playing guitar hero for quite a while so I decided to do some creative things to one of my guitars. I plan on doing more modifications to this controller so stay tuned for updates.

One note: I'm sorry about the low resolution/blurry pictures. I was using my phone to take them.

'Edit: I need to upload the final couple of steps. Check back for a finished instructable soon

Step 1: Parts/Materials/Tools

Parts and Materials:
- Guitar Hero controller (duh!)

The Jack/foot-pedal
- Some kind of female plug (will go into detail about this later)
- A big momentary pushbutton
- A project box (plastic preferably)

"Killswitch"
- A small momentary pushbutton

Misc.
- Solder
- About a foot of wire

Tools:
- Small phillips screwdrivers
- Soldering tool
- Wire-stripper

Step 2: Mod 1: the Jack (Intro)

Because the killswitch will render the select button useless, I needed to make an alternate select or star power button. I thought about just adding a button on the front of the guitar but I like the smoothness of the face so I decided to add a jack and make a star power foot pedal.

Step 3: The Jack (Getting Your Parts)

The jack I used was scavenged from an old A/V receiver. I just cracked open the box and unsoldered it.

Step 4: The Jack (How to Put It In)

Now that you have your jack, find a spot on the guitar where you want to mount it. I chose a place just a little above the strap knob.

In essence, this is just adding another select button.

1. Drill your hole in the place where you're mounting the jack. Take note to make sure that there's enough room on the inside of your hole for your jack. (picture 1)

2. If there are supports in the way of your jack, use a knife to cut them away. (pictures 2&3)

3. Find the select button board (yellowish) and follow the wire to the main (green) board. (picture 2)

4. Solder one wire from your jack to the leftmost of the three contacts on the main board. (picture 4)

5. The other wire from your jack will be soldered to the middle contact on the select/start button board.

6. It is a good idea to tape or hot glue these soldered points because you may rock too hard and cause the joints to break.

Step 5: The Foot-pedal

I didn't have my camera on me so there are no pictures of this being built.

Take your project box and drill a hole big enough to mount your large button. Attach said button to project box. The pedal is really simple but it makes setting off star power a lot easier.

One note: it's a very good idea to angle the bottom of the project box because it makes the button lean towards you.

Step 6: The Killswitch

On a real guitar, a killswitch cuts power to the pickups producing an automatic and momentary silence. On the guitar hero controller, it acts as an alternate strum button.

The connections I use change the function of the select button to that of the killswitch. If you wish to make a killswitch without disabling the select button, just use any momentary pushbutton in lieu of the select button. Alternatively, you can follow my earlier tutorial on adding a jack to the guitar hero controller.

Another good killswitch how-to is located here.

    I would think about using a jack like this to make a foot pedal to the select button so you don't always have to tilt the controller to deploy star power because select deploys star power too.

    that is an amazing idea. or even relocating the button down where you can naturally press it. thank for the idea.

    could u post a link to that plz

    That's actually what the jack was originally intended for. I still need to finish writing up that last part but it'll all be clear soon.

    i noticed that with the uk world tour guitar, the battery drains all the time, this gave me the idea of adding a on of switch that cuts of the battery, so far so good. next stop, rumble pack!!!

    this is really awesome.. I just did this with my sg controller...i used a s/pdif jack..works like a charm!

    One thing that has been puzzleing me..... with the audio jack, do you have to do anything to it to use it as a power cable? Or do u just strip it and solder the wires on? Plz email at qewqwerty@gmail.com

    I'm not quite sure I understand what you mean when you say "power cable." Do you think you could elaborate?

    user

    Call me a n00b, but what I think is that the audio jack type cable is only for audio. but If you strip the wires, can you use that as part of a circuit?

    No. You can pretty much use any jack for anything, provided that it can physicall handle it (don't try putting high voltage/current on a tiny wire connector, etc). Just strip the wires and solder them on.

    thanks!

    i dont know why but this instructable gave me an idea, replace the strum bar with a reed switch and make a magnetic pick. there are some problems with my idea though. first off the switch is either going to be too sensitive or not sensitive enough. it would be really hard to get it just right. also, you would have to put strum up/down buttons on there to control the menu movements. hmm. maybe ill look into this further. thanks for the inspiration.

    That is a great idea! You might think about using a potentiometer or some other variable resistor along with some capacitors to have some sort of control over the sensitivity as well as doing some signal adjustments. I think I might have to go pick up some reed switches...

    you could add a status led inline with the reed switch so you can calibrate without trial and error on gh.

    you can also add real strings (metal ones) and connect the middle one to the ground of the strum bar and the pick (use a metal one) to the live part of it

    that too is a good idea, although id keep it down to 1 string.

    I like things lifelike, but one string is cheaper and much easier (wiring one string instead of all five is so you don't accidently strum 5 times when you want it one time, you didn't ask but I thought I should say it in case others will use my idea)

    user

    If you do that I would use a High E guitar string cuz its easier to strum fast with.
