Audio is switched inside the actual footswitch. A survey of the possibilities.
Sometimes you only need to mute the effect to create a pseudo-bypass. Also includes the opposite idea known as the dry kill mod.
Audio is switched within a remotely driven relay.
Electronic Switching
Part 2: JFETs, MOSFETs/Analog Gates
To create an electronic analog of a mechanical switch we need to create both a toggling device and some audio switching devices to replace the mechanical "poles." These two tasks are broken up into two articles.
