I own a Yamaha electric guitar made in 1985 lawsuit, SBG model as they were called ,Santana endorsed it ,Gibson wasn’t interested, Yamaha set out to prove they could make a great guitar,.The workmanship was incredible, where they fell short was the pic-ups ,Gibson had the sound.
Unbelievable
Yamaha really made this statement:
Glossy black piano finish provides improved signal-to-noise performance

I thought I would seek opportunity to hear these speakers, but now I do not think so
