The newest addition to the Snark line is the Super Tight clip on
tuner. It's LED lit screen is very easy to read with a fully chromatic
tuning range. Very fast and very sensitive for the best tuning of your
instrument. The screen can swivel and rotate to accommodate left or
right handed players as well as many instrument angles.
It also has a built in metronome (just visual, no sound) that can be
useful for finding tempo's and checking your lack of timing out.
