Fast, easy, and accurate.
The Intellitouch PT20 Clip On Tuner is the latest in vibration-based tuning.
It's automatic, chromatic, and displays the measured pitch on a large, backlit display for easy tuning. The PT20 tuner ignores background noise - it feels the instrument's vibration instead of using sound. Works on electric and acoustic guitars, basses, violins, banjos, mandolins and more.
A-Ref adjustment 430Hz-450Hz
