The MT-3 features the following:

LED Tuning Guide shows the difference of pitch (-50 to +50 cents) in TUNE mode. Indicates standard pitch (A=437 Hz to 445 Hz) in SOUND MODE and CALIBRATION MODE.

Digital Display shows notes by Alphabetical character (A, b, c, d, E, F, g). Sharps are indicated by a red dot in lower right corner of the display
(Ex. A# = A.).

Mute Foot Switch eliminates MT-3 output signal for silent tuning. Switch will mute signal when MT-3 Power is ON or OFF position.

Battery Check LED indicates battery life at Input plug in or DC jack in. Stops lighting at lower battery life.

STEPPED UP TUNING
 
MT-3 MICRO TUNER

The MT-3 is a multi-function chromatic tuner that fits in the pocket of your gig bag and won't take up valuable space on your already-crowded pedalboard. The same micro technology used in the Guyatone PT-21 Chromatic Tuner enhances this functional pedal format, making it a versatile and essential professional tool.

The MT-3 works just like any other stompbox - plug your instrument into the input, plug the output into your amp and you're rocking. The MT-3's stomp switch mutes the input signal for silent tuning in either on or off mode, performing double duty as a "kill" switch for your rig. The MT-3's advanced circuitry won't alter the tone of your instrument when bypassed. If you prefer tuning to a reference pitch, the MT-3 can generate tones over a one octave (13 notes - A4-A5) range that can be adjusted at the touch of a button.

All of these functions and more can be accessed quickly and easily through the MT-3's simple "One Touch" calibration. All four modes of operation can be reached by pushing a combination of the unit's Power, Mode, and Select buttons (see instructions for particular combinations).

The MT-3 has four primary modes of operation:

TUNE MODE - Tune by connecting your instrument to the MT-3.

SOUND MODE - Tune listening to standard signal (audio tone) from MT-3.

CALIBRATION MODE - Sets frequency of standard pitch (A = 440 Hz at original setting). A4 pitch can be selected between 437 Hz and 445 Hz (1 Hz intervals)

AUTO CALIBRATION MODE - Calibrates standard pitch (A4) from an external instrument (range is A4 = 437 Hz - 445 Hz)

The MT-3's ultra-bright, digital display is easily visible even on dark stages. The user can select either "bar" or "dot" tuning indicators for the two color, 9-segment LED display. The MT-3 can be powered from an internal 9-volt battery (included) or an external AC adapter. Like all Guyatone products, the MT-3 is covered by a full 3-year warranty.
