Guitar Control Cavity and Pickup Routes Complete
Did you know you can subscribe to free email or RSS alerts of new articles?
Continuing with my electric guitar project, I completed the pickup cavities and control cavity after deciding against the combination of rear routing and front routing that the original Klein guitar uses. I decided rear routing was preferable. I did a quick test fit of the controls and everything looked good.
For the pickup cavities, I made a pickup template out of MDF by forming a rectangle to the dimensions of the pickup. I took advantage of the fact that the router bit can’t get into the corners which results in radiused corners for the pickup cavities. There was no need to complicate the template by trying to radius its corners as well.

Before starting the control cavity, I chose the locations of the controls and used Forstner bits to drill through the top of the guitar body and out the back. The holes then provided a point of reference for the location of the control cavity. I made a control cavity template by gluing up scrap pieces of MDF into the shape I wanted. Once again, I took advantage of the fact that the router bit would leave radiused corners.

The guitar body with all of its routing complete now weighs a mere 3 lb 2 oz. Next up is applying the Danish oil finish.

I don’t understand why you cut holes all the way through for the control cavity…

Hi Danny - thanks for stopping in and thanks for the comment. The holes would have been drilled through the top one way or the other in order to load the controls from the back. This is a rear routed guitar. They have to pass through the face of the guitar. It didn’t matter whether I did this before or after the control cavity - the effect is the same. By starting with the holes, I had them as a reference for positioning the control cavity since I wasn’t completely sure what form the cavity was going to take.
