Photoresistor Volume-Modulating Tremolo: Design and Function

In this second of two videos on Tremolo design and function, the Photoresistor (Optoisolator) Volume-Modulating-type of Tremolo is explained in basic terms. The presentation includes diagrams and narrative to clearly describe the circuit design, tracing of the circuit pathways within a Fender Deluxe Reverb schematic, visual demonstration of varying voltages, resistances, and wave forms within a functioning Tremolo circuit using an analog volt-ohmmeter and an oscilloscope.
