I doubt many of you could afford to buy yourself a self tuning guitar. However, everyone could/can afford the eNote color coded tuner from Eleca.
The color coded display is simple to read as long as you’re not colorblind. Green means your in tune and red means you’re not. What could be easier?
It only costs $25 so if it doesn’t work out well you’re not so far in the hole. It sounds like a great device and I know I could sure use it, I’m horrible when it comes to tuning my guitar.
