Godlyke, Inc.has announced the release of the Guyatone PT-21 palm size Chromatic Tuner. Designed for use with any instrument, the PT-21 is an extremely small and lightweight tuner. It mounts directly to the instrument via a reusable adhesive pad, and will work with any instrument without the need for cables and wires. If mounting to the instrument is not possible, the PT-21 can tune via its onboard microphone and can also generate reference tones over a one-octave range.

All of these functions and more can be accessed quickly and easily through the PT-21's simple "One touch" calibration. All five of the PT-21's main modes of operation can be reached by pushing an easily memorized combination of the unit's Power, Mode, and Select buttons. The PT-21's five primary modes are as follows:

• DIRECT mode -- Tune by sensing vibration, attaching the PT-21 to the instrument
• MIC mode -- Tune by using the PT-21's onboard microphone
• SOUND mode -- Tune listening to standard signal (audio tone) from PT-21
• CALIBRATION mode -- Allows user to set frequency of standard pitch (A = 440 Hz at original setting). A4 pitch can be selected between 437 Hz and 445 Hz
• AUTO CALIBRATION mode -- Calibrates standard pitch (A4) from an external instrument (range is A4 = 437 Hz -- 445 Hz)
