I would like to build this circuit (a tremolo guitar effect) for use with my digital piano. I'm having trouble understanding the role of the highlighted components - especially the interaction between Q1 and Q2.
Also, why did the designer select the type of transistors the way he did - is there an advantage to using the MOSFET/JFET/BJT as shown in the schematic?
