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.
My projects are generally inspired by classic designs, but with a twist. I like to build things like basses on guitar bodies, non-standard scale lengths, and occasionally originals, and experiment with materials, finishes, and electronics. One of my great interests is driving the cost out of luthiery by sourcing parts and materials from the hardware store. I prefer to build more guitars than simply more-expensive guitars.
On the left is my excellent Preval vFan airbrush that Home Depot gave me to evaluate. You can see the hose has a standard 1/4" male QD connector installed. On the right is a pressure regulator, with a standard female QD connector on the outlet side, and a scuba-to-NPT adapter on the inlet side. Plug that into an inflator hose on a scuba regulator, and set your output pressure on the inline regulator.
