Intro: Guitar Hero Controller FIX Extra-Strum(FIX SWITCH)
This is my first instructable, i hope to be as clear as possible.
DISCLAIMER: Before we go any further in the instructable, you must know that this Mod/fix can leave your strum broken, so try this fix under your own risk. I'm not responsible for any damage that may happen.
This is the way i fixed my down-strum switch, which was giving me two strums when doing one strum, causing to miss the notes frequently.
I tried to find how to repair this problem by searching the net, and i didn't find anything helpful other than "BUY A NEW GUITAR". Why should i have to buy a new one just for one darn switch!
So i tried to find the answer myself.
This time i'll be using a 3d representation of the switch, because i thought the switch was broken or something i didn't took any photos coz i wasn't confident that this could work, and then when it worked i was too lazy to reopen the whole thing just to take some pics. (COZ I WAS ROCKING HARD YEAH!)
Note that there are wrong parts in the 3d representation. I did the 3D mainly by memory so there are wrong parts, but the examples are good enough to give an idea of what's inside the switch.
I will update the instructable with photos next time. My up-strum switch will be needing a tuning soon, so I'll take photos of the process.
What You'll Need:
- Guitar Controller
- Screwdriver (that fits in the screws)
- Soldering iron
- Solder paste
- Game to test
Step 1: Prepare Your Guitar Controller.
First of all you need to open your guitar. I used a flat head screwdriver to open mine and worked good.
Once you've opened your guitar you will see the circuit boards, the one we'll be using is in the middle of the guitar where its placed the strumming bar.
We're gonna unscrew the four screws in the middle of the circuit board. I did it this way coz it's still firmly attached to body of the guitar and it serves as a support for unscrewing.
Then we're gonna unscrew the other 4 screws and lift the board.
Step 2: Taking Off the Switch
Once the board is free, turn it to see the other side of it.
Take off the plastic with the holes to free the switches. This plastic prevents the switch to move and break its pins while you're strumming.
Now we melt the solder of the switch we want to fix, try to not delay too much or you can melt the plastic that holds the metal pins.
Take off the excess of solder of the metal pins, otherwise the switch will not open.
Now you have the switch in your hand!
Step 3: Open the Switch
Now we try to open the switch by bending just enough the "T" plastic that holds the two pieces together. Then pull the two pieces and open the switch, take care when doing this step, the inside parts will fall when you open the thing, these parts are two, a spring and a metal "J".
Now we can fix the problematic part.
Step 4: Problem and Solution
Here are the parts you'll find in the switch. The problem is located in the 4th piece of the image, the problem is in the fork-shaped metal.
In the images you can see why the extra-strum is happening. When the white plastic goes down (top of the switch) as you strum, it moves the lever thing of the plaque that at the same time moves the fork pins and this makes contact with the other metal plaque,sending the signal.
In the 5th image you can see the problem in side view, what we want to correct is the inclination of the fork pins by pushing them as in the last image, doing this simple thing will correct the extra-strum and you will be happy. ;D
Step 5: Switch FIXED
Now all that rests is to put everything in place and close the switch.
Remember that this 3D model where made by memory, so there are mistakes in the scale and place of the pieces, but this references are good enough to give you an idea of whats inside.
Put the pieces back in the plastic case, close the switch and re-solder it to the circuit board. Connect your guitar to your console or PC and test the switch with your finger, if you're satisfied with the feeling of the switch, then you can proceed. Put the plastic holder of the switch and screw the plastic to the circuit board. Then screw the other four screws and put the cover of the guitar and screw till its finished.
NOW ROCK ON MAN!!!! YEAH!!!!!
I hope this instructable was helpful and easy to understand. Thanks for watching it and/or comment.
