Lesson 2: AC signals, capacitors, inductors, impedance, AC circuits and AC circuit analysis, simple filters (high-pass, low-pass, band-pass)
Week 4
Lesson 1: Electric guitar electronics, pickup design, volume control circuits, tone control circuits, pickup placement, frequency content and tone, wah pedal, talk box
Lesson 2: Converting electrical signals to sound – loudspeakers.
Week 5
Lesson 1: Designing speaker enclosures, basic principles, interaction of speaker driver with the cabinet, why a cabinet at all? Closed-box speaker design.
Lesson 2: The ported / bass reflex speaker design.
Week 6
Lesson 1: Overview of a simple guitar amplifier, preamp, volume control, tone control, gain and distortion, tube circuit distortion, power amp section.
