The benefits of a larger LCD display and the ability to tune down by 4 semi-tones for sweetened
tuning are standard on the PU20 Clip Tuner. Plus the large LCD display is backlit and the PU20 features a piezo microphone. The extremely accurate tuner can be mounted just about anywhere with its four hinges. Need your tuner locked firmly on a guitar headstock, music stand or tree branch? No problem! Just Clip it!
