The New Intellitouch® PT40 Rechargeable Tuner

Combines vibration-based tuning with a Lithium Ion rechargeable battery! It is automatic, chromatic, and displays the measured pitch on a large, backlit display for easy tuning.The PT40 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 USB charging cable (included) enables fast charging. 

The PT40 has a retail price of $49.95 and a Limited Lifetime Warranty.
