D'Addario Planet Waves PW-CT-05 Chromatic Tuner Metronome

Planet Waves proclaims this Chromatic Instrument Tuner and Metronome to be "The ultimate practice workstation." Give it a workout and you'll probably agree.

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. They slow down and finally stop as you nail the pitch. In Sweep mode, the LEDS sweep left or right indicating whether you're flat or sharp.

Planet Waves has built in all the extras to make this tuner and metronome a full-featured training tool. These 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.
