Designed to tune electric and acoustic guitars, basses, violins, banjos, mandolins and more without interference from ambient room noise, 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 vibrational energy instead of relying on sound. And, the swivel allows a perfect view of the backlit display. Intellitouch learns and remembers. It uses the latest in digital technology to adjust the tuning reference to any frequency you want, and it stores the "learned" reference in the preset even when it is turned off! Intellitouch is ideal for everyone. Its ease of use and reliability is what beginners need and professionals want.
