The TC-8 from TASCAM is the ideal tuner and metronome for educators, students and professionals. The chromatic tuner features a fast detection chip and 5" wide, backlit LCD display for instant pitch feedback. Four display modes are available for the clearest display. The tuner can be calibrated to a piano or other installed source, and eight tuning modes include historic and alternate tuning modes for period instruments. An oscillator plays through a built-in speaker for groups or classes.
