This video finally got me. I got to have one of these.

The Moog Gui­tar pro­vides an incred­i­bly inti­mate play­ing expe­ri­ence that con­nects musi­cians directly to the source of the sound; the strings of the gui­tar. It does this by con­trol­ling the way the strings vibrate. In a very coher­ent way, it gives energy to, and takes energy away from the strings. The result­ing tim­bres do not rely on effects or post-processing. They are cre­ated directly from the strings.

Just kick­ass.
