Tascam TC-1S

The Tascam TC-1S is a chromatic guitar/bass tuner that operates mostly on an internal solar cell. It also features a USB port for use indoors, an integrated microphone and a quarter-inch jack for direct plugging in of guitars and basses.

Additionally, the TC-1S sports a nylon strap and clip and measures in at 3.77- x 0.71- x 1.57-inches, making it extremely portable.

The TC-1S is capable of running entirely on solar power, offering quick on-the-spot guitar tuning throughout the day while its USB port allows it to operate without the sun's solar power. Its integrated microphone and quarter-inch jack allow most electric and any acoustic instrument to be tuned. The Tascam TC-1S is available in black, pink, orange, green, blue and white.
