Rock Band Guitar Mod: Guitar Hero Buttons and Strum Bar

Step 11 Wedging the Guitar Hero Button Piece into the neck of the Rock Band Guitar

We're almost done with the "hard" part!

I put hard in quotes, because it's not actually too difficult, and it's all really low risk.
Of course, if this is your first time with a Dremel and a soldering iron, I bet you're working up a sweat! Don't worry so much, the real value of a project like this is the process, and the education it gives you!

Also, the ladies like a man (or a woman) with a custom GH controller.

Notice that the Guitar Hero circuit board still overlaps the spot in the guitar where it is supposed to fit.
This is okay. In fact, this is good. we will use that to ensure a tight fit.

At this point, I put a little hot glue over the ribbon cable connector solder points on the guitar hero button control board. We've been moving the wires around a lot, and I'd hate for those tiny cable ends to break from stress. the hot glue will hold it all in place for us. This is optional.

NOW, wedge the button control board from the PS2 Guitar Hero button set, UNDERNEATH the LOWER rock band button control board.
then lay the PS2 buttons flat on the neck of the guitar.

There will be a little overlap with the top. this is fine.

Gently separate the top Rock Band Fret Buttons from the Back of the neck, and wedge the overlapping guitar hero button control board in there. Check your fit. If you think it will help, try dremelling down a bit of the top of the GH button control board.

After this, it will stay in place pretty well. You may want to test teh buttons again at this point, to make sure nothing was pulled lose or cut.
