Hi Im trying to understand the DeadAstronaut Reverb circuit but dont understand the jfet switching circuit, can anyone help me ? (Mainly I dont understand the diodes part)
JFET transistors can be used as switches. When supplied voltage, signal can go through.
The diode, capacitor and resistors avoid brutal changes in voltage to avoir pops and clicks.
Here is a nice post by RG Keen: https://www.premierguitar.com/articles/jfet-switching-1
