The PU20 is designed to tune electric and acoustic guitars, basses, violins, banjos, mandolins, and more without interference from ambient room noise. It does it all without the use of wires, microphones or pickups. Tuning in noisy environments is a snap because the unique, flexible clamp actually feels the instrument's vibration instead of relying on sound. PU20 features backlit large LCD display for maximum visibility even in the dark stage.
