The WMT-588C+ features Cherub’s proprietary fast tuning software to make this new tuner more accurate, quicker and easier to use than 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 an extended tuning range from A₀ to C₈, A₄ calibration from 410Hz to 490Hz, 20ms fast response real time tuning, flat tuning and PowerSave, which dims the display without shutting off the tuner.

Also included in the WMT-588C+ is a metronome with seven rhythms and 10 beat variations to make practice more effective. To help train the users ears, there is an adjustable frequency tone generator.
