ABOUT TURBO GUITAR

I come from a family of visionaries and inventors. My grandfather spent his after-work hours developing a new refrigeration concept back in the early decades of the 20th century when cooling was still being done with ice. My dad had his first big success while still in his twenties, as part of a team that developed a frictionless rocket fuel mixer. I am a low-tech guy; I prefer simpler things such as guitars.
