The PLL-4046 is a monophonic analog harmonic synthesizer effect.

That turns your input signal into a square wave and then has a multiplier

and divider that add intervals to your note. Two harmony notes are

controlled by the loop function, which controls how it tracks your original

note.

• Makes one note into a chord

• Make any triad out of one note

• Makes it sound like there's someone else playing along with you

• set the loop control to decide how it follows your playing

The three notes are a three-channel mixer that gets into a master

volume. PLL is capable of the kind of ragged polyphony and noisy

collapse you’d hear in an ’80 s arcade game like Missile Command, with

descending laser-beam pitch glides and vocal roars as notes decay. The

heart of this pedal is a CMOS Phase Locked Loop (PLL) IC – CD4046.

In a nutshell, the PLL takes your input signal and compares its phase

and frequency against an oscillator, generates an output proportional to

their difference then feeds it back to the oscillator. This then causes the

oscillator to lock onto the input signal and generate a synthesized

frequency.
