This twelver is a mashup of a number of different models. The body is Danelectro-style masonite over chambered plywood, with Tolex binding. The headstock is interleaved Rickenbacker, the bridge is more like a Gibson, while the overall style is my typical Audiovox.
These are the two main templates I used to build all the Audiovoxen. The image is straight from the camera, simply save it and print it out at the proper scale. The dimensions of the body template are 17" long and 11-1/2" wide. The overall length of the headstock template is 10-7/8". The neck pocket is Fender-standard.
This is my own original design, it is inspired by the old Audiovox, but not copied from it. My original design was an accurate copy, and it didn't work very well. Therefore, nothing needs to be exact if you want to build one of these, there are no official factory specifications.
