摘要： An electronic tuning device includes a display with a single row of LED's corresponding to musical notes wherein the sensing of a fundamental frequency of an input tone causes the operation of the corresponding LED to indicate the nearest note. Additionally the LED is operated in manner, such as blinking proportionally to the variation from the note and/or producing different colors, such as green, red and amber, to indicate in-tune and out-of-tune conditions. A double back adhesive rubber pad can be used to removably mount the tuner on an instrument, so that the device can simply pulled off the musical instrument to make it ready for its next use. The rubber pad serves to attenuate high frequency mechanical vibrations of the musical instruments thus improving the accuracy and versatility of the unit. In one embodiment, the display is mounted externally on the musical instrument while the tone sensing circuitry is mounted inside the musical instrument such within the sound box of an existing guitar.
