Korg’s Pitchclip is a first-rate, no-fuss clip-on for beginnners and pros alike. It offers simple functionality, a bright LED display, and is nearly unbreakable. It’s also smaller and lighter than many popular tuners.
Peterson’s new clip-on is a seriously amazing tuner, with superb accuracy, loads of alternate “sweetened” tunings and a jumbo calibration range. It also has Peterson’s trademarked LCD virtual strobe display.
