Gibson Min ETune 2014 demo

Min-ETune is one of the simplest, most accurate lightweight tuning systems in the world. Min-ETune is a small compact battery powered tuning unit that sits on the back of the guitar - a mighty enhancement to an already great instrument. No need for screws, wiring or routing, in fact the system is hardly visible from the front of the guitar. You can still adjust the tuning pegs manually or turn on the Min-ETuneTM to choose from 12 popular tunings or program 6 of your own.
