Planet Waves PWCT06 Tuner

The revolutionary Planet Waves SOS Guitar tuner sends two out-of-phase LED light beams directly onto the vibrating string.

When the string is out of tune, the two lights visually dance on the string being tuned. As it approaches tuning, the movement slows down and eventually stops when it is perfectly in tune.

This revolutionary visual tuning system allows for precise tuning in quiet or noisy environments, without the need for audible sound or detection of any kind. It features an ergonomic design the size of a guitar pick.
