well from the pic you can see that, thats about as far as I've gotten (considering I started this in the winter and I hate working in the cold!!!) but...
This is a picture of my "not so complete guitar" but it is a start... I always loved old school rock and also most modern rock and recently am learning I just thought my old used guitar could use a "makeover"
Step 1: Design
Find a design. I used a Paul Stanley aka Star Child design, but you can Google different designs. find one you like next sketch the design on to a poster board. make sure you like the look, feel, and make sure that it will be comfortable!!! next get some MDF from home depot. I used 1/2" and another piece of 3/4" (shown in picture). but trace the design you drew onto both pieces wood. now the power tools!!! cut the designs out w/ either a 1. a ban saw 2. a saber saw or 3. scroll saw. both of the pieces don't have to be perfect just similar. (I'll explain later)
Step 2: Gadgets
I used old switches and gadgets but I'm pretty sure they can be bought at Radioshack (I love Radioshack) but I have 1 switch 4 knobs and one female / output jack. to put it together you will need some wiring diagrams (below) these are the wiring diagrams I used not to hard to understand. after your drive to Radioshack stop over at Lowes or home depot and pick up some heavy duty plexi glass. this is where the hum bucks and knobs etc are going to go.
