Well, I can tell you, I wouldn't design an analog switch that way. But I would most likely be designing a proper analog switching circuit, not a effects pedal.Just from this framing alone, we have...

The purpose of D3 is to prevent the JFET junction from ever being forward biased, at least not to the point where significant current from the switching signal gets injected into the audio signal...

The diode prevents the gate pn junction from forward bias when the input to R16 is 9V.This allows the gate voltage to rise to equal the drain and source 4.5V. Which is drain and source is not indicated...

What is the purpose of this diode in the gate of a JFET
I am studying how the bypass circuit of the Tube Screamer pedal works. It is dependent on two JFET transistors that are used as switches. I am not great at understanding JFETs as switches, as I have...
