Solar-rechargeable tuner from Tascam

Tascam TC-1S is the world's first solar-rechargeable tuner. Tascam TC-1S charges its battery from a bank of solar cells on the front panel, and a USB input is also available for quick-charging when you're completely in the dark. It's wrapped in a shock-proof silicone cover that's available in six colors and keeps the unit protected.

The TC-1S has a built-in microphone as well as a 1/4" input for guitar and bass tuning. Its lightning-fast pitch detection is displayed on a wide bargraph display for instant feedback. Four display modes are available, including fine pitch display for 1-cent accuracy and strobe tuning animation. The tuner can be calibrated to an external source such as a piano or other hard-to-tune instrument.

Included with the TC-1S is a nylon strap and clip. Snap it to your guitar or bass gig bag and it will stay charged all the time, every planet-conscious musician is going to need a Tascam TC-1S.
