Title: Electronic musical instrument tuner - compares instrument frequency with internal standard giving optical indication of beat note using LEDs
Inventor: DESPOTOV ISIDOR
IPC: G10G7/02
Filed: 1977-03-04
Abstract: The electronic tuning indicator is for musical instruments and operates over a range of nine octaves.
