Self tuning guitars

If you are anything like me, I hated having to retune my guitar after a performance, I also hated manually having to change the tuning when playing out of standard. What I want to invent is a self tuning guitar with tons of features to compete with leading brands. This would only be one design of the guitar I want to design, it will also have an array of effects to choose from build into the guitar itself. I believe this would create a super instrument unlike ones ever been seen before.
