The WMT-578 features Cherub’s proprietary fast tuning software to make this new tuner more accurate, quicker and easier to use than other models in this category. Features include a large LCD display that not only shows the note but also displays a meter to help tune to the correct pitch. Other features include a built-in microphone, an extended tuning range from A0 to C8, A4 calibration from 430Hz to 450Hz, 20ms fast response real time tuning, and PowerSave, which dims the display without shutting off the tuner. Input and output ¼ inch jacks and a mini headphone jack complete this flexible package. To assist with tempo training, the WMT-578 includes a metronome with a tempo range from 30 to 250 BPM, multiple rhythms and beat variations to make practice more effective and fun. All rhythms are displayed along with a pendulum style metronome on the blue color LCD.
