My son got this for Christmas: fancies himself as a rocker so its fun design fits with his 'image'. He uses it on an electric as well as an acoustic guitar. My daughter also uses it on her ukulele. Stays tight on the headstock and works reliably....so I am told.
This tuner is fantastic. Small, very accurate and you can't beat the rock and roll hand sign. It also comes with lithium battery that will last a long time. It is a unique tuner I have never seen and love it. I highly recommend the product. Thank you and Rock On!!!
