Title: Tuning changer for electric guitar - provides higher and lower tones by moving program and adjusting screws to adjust individual string tension
Inventor: RUDNIK WITOLD
IPC: G10D3/14
Filed: 1991-06-28
Abstract: The tuner allows the tones to be raised or lowered simultaneously or independently from each other. The individual stringing is carried out by a program (23) which is moved by arms (21).
