I’ve been playing the guitar ever since I was a kid, so I’m pretty good at it by now. But the one problem I’ve always had is getting my guitar in tune and keeping it in tune. It’s very time-consuming having to tune the guitar using pitch pipes; time I would rather spend actually playing the guitar. Then my wife found this great little gadget called the String Master Robotic Guitar Tuner. All you have to do is slip it over the end of the tuning peg, and it does the tuning for you. Now it just takes me a few minutes to tune my guitar, and I’m good to go.
