Planet Waves proclaims this Chromatic Instrument Tuner and Metronome to be "The ultimate practice workstation." You can choose between Strobe and Sweep tuning modes. In Strobe mode, the played note appears in green on the 12-segment rotary display while red LEDs chase clockwise if you're sharp and counterclockwise if you're flat. In Sweep mode, the LEDS sweep left or right indicating whether you're flat or sharp. This tuner and metronome include a pitch pipe, timer, stopwatch, and a very capable metronome that generates a musical woodblock tone and has programmable beats per measure, beat subdivisions, and a handy tap-tempo function for locking in to a beat. A condenser mic, 1/4" I/O, Copy Pitch feature that adapts to various instruments, and extended 415Hz to 466Hz calibration let you tune pretty much any instrument while a 1/8" headphone jack enables quiet practice. A retractable easel positions the unit for best visibility.
