The TC-1S instrument tuner, from TASCAM, 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 silicon cover, available in six colors, and a strap and clip keep it charging all day long on your gig bag.

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, and the tuner can be calibrated to an external source.

MSRP: under $40.
