Tascam TC1S-BK Solar Powered Tuner Black
The Tascam TC1S is the world's first solar powered tuner. This Earth-friendly guitar accessory is always ready to use with a solar recharging panel mounted above the large LCD display - no harmful batteries to throw away. You can even quick charge the TC1S through a USB connector when you're totally in the dark.
Input can be selected from a built-in microphone or 1/4 inch guitar/mic input. A guitar strap clip and silicon rubber case makes the TC1S durable enough for the road. A must-have accessory for every ecology-conscious musician.
