TaylorSense is a smart battery box equipped with sensing technology that monitors your Taylor guitar’s humidity, temperature, battery life, and impact incidents. The battery box replaces an existing battery box on Taylor guitars featuring any of the following onboard pickups with a 9V battery: Expression System® 1 or 2, ES-T, or ES-N. In addition to tracking the guitar’s condition, TaylorSense uses low-energy Bluetooth to send your guitar’s data to the free TaylorSense Mobile App – available for both iOS and Android devices – which sends push notification alerts when the guitar needs care. The timely alerts include links to easy-to-follow videos created by Taylor’s experts that show you how to solve problems when they arise. The TaylorSense Mobile App is compatible with most iOS and Android mobile devices and operating system versions. Installing the battery box is easy thanks to simple instructions, or you can have an authorized Taylor service technician do it. Not sure whether you have a compatible Taylor pickup in your guitar?
