The best Snark yet! Brighter, easier to read display, faster response and extremely accurate. Takes \"Snarkiness\" to a whole \'nother level. Easy to use and highly recommended. Has the tap tempo metronome and calibration features found on the SN-1 and SN-2 Snark models. Tunes all instruments; fully chromatic. Does not have the switchable mic found on the SN-2.
