(Specially for my friend Pat )
Ibanez, Boss and many others have not chosen to implement 3PDT true bypass, but instead transistors based flipflop circuits in their effect pedal. Probably because it’s cheaper !
See the following schematics (many thanks to Tonepad, GeneralGuitargadget, Steve Cerutti, R.G. Keen, Jack Orman) …
First, see Steve Cerutti (GGG) TS808 schematic (I surrounded in red the flipflop circuit) :
Then, have a look on tonepad schematic, implementing 3PDT for true bypass :
