laser-synthitar from a guitar-hero-like toy guitar

Step 3 Prepare the toy guitar

First i took out the original pcb and removed the buttons on the body. The fret buttons needed to be rewired. There were less wires than buttons coming out of the neck and some diodes were soldered in. I took these out and soldered one wire to each button and one to the common ground, sry no pics of this step but that's easy and may be different on another toy guitar.
