The Intellitouch® PT10 "Mini" tuner pushes forward the boundaries for small, compact size while still having a large, easy-to-read backlit display. The PT10 tuner ignores background noise - it feels the instrument's vibration instead of using sound. It is designed to clip on electric and acoustic guitars, basses, violins, banjos, mandolins and more! The Intellitouch® PT10 is available from your favorite music store, as well as directly from OnBoard Research. The PT10 has a retail price of $39.95 and a Limited Lifetime Warranty.
