***Please Note***
I want to make it perfectly clear that these are QUICK FIXES and not PERMANENT SOLUTIONS. If you don't want to send your (only) guitar back to EA and wait 9-10 days for it to come back, these fixes are perfect for you to do! You can keep on playing and send the guitar back at your convenience. I strongly urge you to send your guitar back to EA and get a replacement as soon as possible if you have encountered any of these problems.
If some of these descriptions don't make any sense, I can post pics or something to make it more clear.
***Double Strum Quick Fix***
Recently, I encountered the infamous double strum problem where strumming on the downstrum causes the game to recognize two strums instead of just one and thus making it impossible to keep streaks going even though you are playing perfectly. I opened up the guitar and looked closely at the strum bar.
The strum is recognized through two parallel plates. When the strum bar is hit, it puts pressure on the metal plates. Each plate has a small metal piece that sticks out, and when these two metal contacts touch each other, it creates a short, which registers the strum. I'm not sure what these pieces are made of, but I'm pretty sure it's sauder. The sauder is what causes the doublestrum problem.
Usually, the pieces of sauder are flat, so when you strum, it registers clean. However, after some time of rough play (or any play in general it seems), one or both of these sauder pieces lose their uniform surface and become U-shaped so there are two smaller contacts instead of one. For me, only one of the surfaces was U-shaped (the one closest to the strum bar). I confirmed the original rectangular shape of the sauder by observing the upstrum parallel plates, which were pristine as compared to my downstrum plates.
So here's the fix: I took a nail file (sandpaper works too), and GENTLY smoothed out the sauder contact surface so it became flat again. Don't push too hard otherwise, you'll take all the sauder off and you'd have to press the strum bar pretty hard to get the note to register. After adequately smoothing out the surface, I put my guitar back together, played a few songs, and confirmed that this fixed my problem. My strum bar no longer registers double strum notes.
***Whammy Bar Quick Fix***
The whammy bar also broke for me too, ironically while I was playing a song on Easy just for kicks. I opened up my guitar to see what was the problem. Just as you would expect, the whammy bar is operated by a simple spring. If you imagine a simple spring, one circumference on each end is folded upwards to be vertical to the rest of the spring. This way, the spring hooks on to the whammy bar and the guitar base. My whammy bar broke because the part of the spring that attached to the whammy bar broke.
Now the part that broke is only ONE circumference of the spring. After opening up my guitar, I eventually found the spring running around freely. I took my fingernail and bent another circumference of the spring to make it vertical to the rest of it. I then attached the spring back to where it was supposed to be, and everything was good to go! Of course, the spring is a little more stretched now that it has one less rung to operate, but I've used the guitar for a week since it broke, and no problems as of yet!

Be advised that opening your guitar voids your EA warranty.
Hello,
While i was in the states (im from Europe) i picked up Rock Band for my PS3.
Cool game, but like many, i got this double strum problem.
Im pretty much in trouble. EA will not help me because i live in Europe. I can't use my old GH3 guitar. And i can't buy a new one unless i buy a overpriced one on ebay wich most likely will have the same problem.
My only fix will be your tip, but can you provide some pictures? it will help alot.
Thanks

Zimz,
This thread is an excellent reference with pictures.

There are three possible ways (as I can tell) to fix your guitar doublestrum.
1. The method described in this post. (Evening out the Metal Contacts)
2. The method described in the post shown above. (Rotating the Tension Screw)
3. The method described in the below post (Inserting cardboard)
http://www.gamespot.com/xbox360/puzzle/rockband/show_msgs.php?topic_id=m-1-39685958&pid=938870&page=0
In the Mythbusters section, from thread showing method #2, he recommends against using my method (#1) and the method #3. I also do not recommend using #3, but it's important to note that it is an option. The cardboard puts added pressure on the metal contacts, which may or may not cause additional defect after a long period of time.
Personally, the tension screw housing was not rotated in any way in my guitar so doing his method wouldn't work for me. I do see method #2, however, as an perfectly valid an appropriate fix for the guitar strum, but it requires some calibration. Obviously, you don't want to rotate it too close or too far from the strum bar. My guitar had a "U-shaped" metal contact so the nail file method worked for me.
Make sure to correctly diagnose your problem before applying any of these fixes. If a metal contact is misshapen, GENTLY file it down so it is even again. If your metal plates are at an angle, apply method #2 to realign them correctly. I would advise against method #3.
I hoped this help, and good luck!
Thank you.
I did #2 and it now seems to work for me. I hope it will be a longterm fix until its released in europe.
Again thanks for your help.

Good stuff, but I've got an even easier Quick Fix for the whammy bar: a rubber band. Don't even have to open the guitar.

Opening the guitar doesn't void the warranty.

According to the warranty sticky post by an admin, opening your guitar DOES void your warranty.

How would they check if you opened your guitar or not?
Also, here is an excellent step-by-step instructional video on method #3 to fix the doublestrum described above (uses masking tape instead of cardboard)

For the first one, wouldn't the sauder just bend again?
And when it did that, you'd either have to fix it again or send it back, but, of course, you can't because you opened up the guitar.

At first my guitar played fine, but then the symptoms started occurring. Thankfully, I recalled reading this thread and carefully repeated the task, using the finest grit sandpaper available...
I cut a small rectangle of sandpaper, folded it in half so that both outer surfaces had a sandpaper finish, stuck it between the contacts, gently pressed the strum bar to cause contact between the solder-points and sandpaper, and then gently sanded perpendicular to the points until I was satisfied with the resulting flat contact surface.
I doubt the contacts were ever flat to begin with, which means you will wear them down unevenly eventually, but once you sand those contact points flat yourself, I don't really see the problem recurring... In other words, once one flat surface makes firm contact with another flat surface, there is "theoretically" no more wear due to friction.
I think it's a great fix... thanks for the useful info.

*****DO NOT DO THE STRUM FIX*******
that is a very very bad Idea the contacts are fine the problem lies in the pad behind the contact being to small so that the contact is being bent out. put some tape peices or other material to make the pad bigger so that the contacts are parrell this is the only problem with the strummer the contacts are fine from the factory I repeat do not file down the contacts its a very very bad Idea.

Oops. Too late!... I guess the fact that my guitar NOW plays better than it ever did BEFORE means that I must have screwed it up completely by taking the man's advise, and the better option would have been to wedge foreign objects inside the guitar? :rolleyes:
If you take the chance on smoothing your contacts, just make sure to only remove a minimum amount of material. Don't file down all of the contact and be left with nothing but the metal tabs.
