I only carry one tuner. It’s this one. You should have one of these in every instrument case you own. I’ve tried the others and the pain of living with them still scars my mind. (Admittedly, I’m not using my mind for anything important, but still it hurt.) Buying a good tuner will change your musical life. Call to come try one out. Call or text 303-984-0777 for an appointment to rawk.
