Step 1: Parts and Tools
For this Project you will need...
Korg Kaossilator (They are usually yellow but there are limited edition pink ones available too)
RedOctane Guitar Hero Les Paul Controller (It fits perfectly into these models and the removable neck and faceplate make it easy to remove the Kaossilator.)
1 IDC Female Socket for Ribbon Cable
Ribbon Cable (at least 10 conductors)
.1 Inch Header Pins (Double Row)
Proto-board (I get mine from a seller on ebay)
50k Ohm Resistor
1/4" Stereo Output Jack
Les Paul Style Jack Plate
4 #4387 Gibson style pickguard screws
Stereo RCA Audio cable
Great Stuff Expanding Foam Insulation
Small Pliers (not needle nose)
Hacksaw Blades (different sized teath cut different plastics better)
3/8" Skew*SHARP! (For cleanup work)
PanaVise Junior Clamp (#ci0011)
Hot Glue Gun
Step 2: Sticker Removal
To remove stickers from your guitar without leaving behind a sticky residue, I would recommend using Goo Gone. Apply the goo gone to the sticker while it is still whole. Let it soak in for a minute or two and peel off the sticker. Wipe it down after. It is also safe to use rubbing alcohol or WD-40 to clean up the sticky residue.
DO NOT USE: Acetone (nail polish remover), Goof Off, heat, gasoline, lighter fluid, paint thinner, turpentine, or razors. They WILL either scratch and/or leave the plastic cloudy.
WD40 worked just fine for me.
Step 3: "Break It Down Now Yall"
Now that you have the controller in pieces, set everything aside except for the top half of the body. This includes the faceplate. You are going to need to break off a few things in order to
1.) make room for the Kaossilator
2.) make that plastic easier to saw through.
There are two techniques I use. For the little stubby poles I just take some pliers an rock them back and forth until they snap off. For long lines of plastic I peal off sections at a time.
Step 4: Cutting Pt. 1
There a bunch of ways to cut plastic and I've tried most of them; hot knife, Dremel Tool, scroll saw, etc. The problem is those methods produce a lot of heat and this plastic will melt and make a mess of your project. You know how when you bend plastic it turns that white color? Well those are little stress fractures that weaken the plastic and we are going to use those to our advantage. The technique involves cutting two lines then using an exacto knife with a straight edge to score between them and then breaking the plastic at that score line. Lets practice on the strum bar housing. See the pictures below.
I sometimes need a little more leverage so I use vice grips. Work from one side to the other.
I made these cutting templates in Inkscape. They aren't perfect but they're darn close.
I like to mark out the corners then use a straight edge to connect them. A red Sharpie shows up well. Use the skew for touchup.
Step 5: Cutting Pt. 2
I use the skew to cleanup any unevenness.
Step 6: Foam
Step 7: Soldering Pt. 1
1.) Desolder existing wires (I cut them so I can pull them out one by one)
2.) Solder ribbon cable to the neck connector
3.) Solder the 10 pin header in the center of your protoboard
4.) Look at the back of the neck connector. There is one wire with a square around it and only it. For instructional purposes this wire is 1. In my picture its the grey one all the way to the left.
5.) Depending on what kind of controller you're using, refer to the corresponding diagrams a solder wires to their correct pins. The "X"s mean nothing is soldered.
6.) Hot glue your protoboard to the body.
Step 8: Soldering Pt.2
You need to look at these pictures for reference.
Wire it as shown in the diagrams below.
Folding the wire in strategic places keeps everything tidy. You will need to cut a hole in the side of the top portion of your Kaossilator. I used a little drill bit and the skew to clean it up.
When once you've fed the wire out of the hole and closed everything attach the 10 Pin connector by applying A LOT of even pressure. Make sure to line up the triangle on the size of the connector with wire 1.
Step 9: RCA to 1/4" Stereo
Step 10: Sustainer

Step 12: Green
Besides, these things were useless from the start :]
