ABSTRACT:
A combined pick and stringed instrument tuning device includes a relatively flat, substantially rectangularly shaped housing having a pick attached thereto and is small enough to be easily held in one's hand. A momentary contact push-button switch mounted on top of the housing controls an electronic tuning circuit by selecting one of several predetermined frequencies from a frequency generator. In one embodiment, the tuning circuit is mounted in the housing so that the tuning device is totally self-contained. Alternatively, the tuning circuit is remotely located and is controlled by a cable connected to the housing or by radio signals. The frequency selected is displayed on the housing and the frequency generator drives a strobe light located near the pick. In another embodiment, a microphone mounted on the housing converts sounds from the string being tuned to a signal which is compared to the preselected frequency. One light on the housing indicates when the string frequency is too high and another indicates when it is too low.
