FT-2 Digital Chromatic Tuner
The Fishman FT-2 digital chromatic tuner provides quick and accurate tuning for most instruments with a simple flip. Clip it on, flip up the display and the FT-2 powers-on. Flip it back down after done tuning to shut it off. The large, high-contrast, backlit display is easy to read and shows pitch with ±1 cent accuracy via tuning "needles" and a multi-color backlight.
It is also incredibly lightweight - weighing only 21 grams - so it won't affect your instrument's tone. When flipped down to the off position, it's very low-profile, so you can leave it place while you're playing and the soft clip is safe on most finishes.
