1. Circuitry of the Electric Guitar Eric Johnsen

2. The Magnetic Pickup  Voltage generator  Inductive coil around magnet Picks up fluctuations in the magnetic field from vibrating strings

3. Shielding  RF Noise  AC Mains Hum

4. The Humbucker  2 single coils  Wired electrically out of phase  Cancels interference

5. Controls  Pickup Selector  Volume  Tone

6. Tone  Harmonic Series  Resonance  Sustain  Passive Filters Inductive Components Capacitive Components  Loading

7. The Complete Circuit  Pick up  Tone controls  Cord  Load

8. Buffering  Impedance Matching  High Impedance  Unity Gain  Preamp / Distortion

9. Active Pickups  Piezo-Electric  Optical  Preamp

10. Summery  Single Coil vs. Humbucker  Loading  Active Circuits
