The 4046-M is an amazing pedal inspired by the old Schumann PLL. The PLL was very rare and expensive analog harmonizer that turned your input signal into a square wave and then had a multiplier and divider that added intervals to your notes. The two harmony notes were controlled by the loop function which controlled how it tracked your original note.
Essentially it is a VCO (voltage-controlled oscillator) that tracks the incoming signal’s phase and locks onto it. It then splits the oscillator signal into two harmonic voices with different intervals for each synth voice. Then it’s put through a very unique and primitive modulator circuit which then can be totally mangled or can create very unique and useful sounds.
