PLANET WAVES PW-CT-06 GUITAR TUNER

S.O.S. Tuner With Strobe-On-String tuning technology
In the revolutionary Planet Waves S.O.S. Guitar Tuner* two out-of-phase LED beams are projected directly onto the vibrating string. When the string is not in tune, the two lights move rapidly across it. As you get closer to the correct intonation, the movement slows down until it stops. This revolutionary visual tuning system allows you to silently tune an instrument in quiet or noisy environments.
• Accurate to +/- .1 cent.
• Automatic shutdown to preserve battery.
• Uses 1 CR1620 battery (included).
*Only for 6-piece guitar in standard tuning. And for 4-, 5- and 6-string bass.
