Dear All,

I'd like to make a ring modulator guitar pedal something like the Fairfield circuitry randy return. Does anyone know of a good circuit or have any experience with a project like this? Thanks in advance

 

Googling 'ring modulator schematic' gives several hits. This one gives useful info as to some of the problems you may meet.
