The Yamaha Live GH-1 pickup is a passive Alnico 5 humbucker made in Japan with 0.06 mm wire gauge and 2x 5500 turns. The 1990 Yamaha catalog mentions "The "Live" series passive pickups employ selected Alnico magnets. AlnicoV in the humbuckers and Alnico II in the single-coil designs - for an optimum combination of power and harmonic structure. ... The humbuckers deliver solid mids and lows that provide an authoritative sense of depth and power."
