The Alumitar was created by Paul Rubenstein. Imagine a guitar neck with no back, the curve of the fretboard going all the way around, now take away the frets and you have the Alumitar. It looks like it is made from an aluminium tube, it has 10 strings evenly spaced around the outside of the tube.

Gibson is selling self tuning guitars. The Powertune system was developed by German engineer Chris Adams, and is being distributed by Gibson as an option on their guitars, with a price tag of $899.
