I played one last week. It took only a few minutes to figure out how to tune the guitar. I was wondering how often the batteries need to be changed.
You don't change the batteries. You recharge them through the gutar input.
For all of the complaining I have done about Gibsons staying in tune I left the store thinking the Robot was a pretty cool innovation. I was able to tune the guitar rather quickly and my only concern was battery life.
