Spectrum III

Notes

This wiring diagram is taken from a 1984 Matsumoku Spectrum III

  • The volume pot is 500K log
  • The tone pots are both 500K log
  • DPDT pull switch
  • The single tone capacitor C1 is a 0.047 microfarad Mylar cap – only one is needed as there is no switch position where both tone controls are in circuit at the same time
  • The phase switch operates on the centre pickup as whenever a switch position is selected where 2 pickups are on at the same time one of them is always the centre pickup
  • Pickup specs
    • Neck: Hammer I (MMK45, 2 core wiring), DC resistance 11.18K
    • Centre: Super II, DC resistance 5.73K
    • Bridge: Hammer I (MMK45, 4 core wiring), DC resistance 11.59K
