Two great items for every musician from Korg! 

The Korg MA-30 compact metronome uses an LCD meter simulating a pendulum motion. Includes a tempo range from 40 to 208 beats per minute in single increments, accented and subdivided beat options, and a tap function that lets you set the tempo. Also generates 12 pitches in an A-413 to A-445 calibration range.

The CA-30 chromatic auto-tuner has a large calibration range from A-410 to A-480. This compact tuner includes an LCD simulating a needle meter, LED guide lights, and an eight-octave tuning range. Also generates 12 chromatic tones in the full calibration range.
