Sovereign is a phase-locked loop "pedal" / "effect" / "sound generator", based off a DTMF (dial tone multi-frequency) tone decoder IC by Phillips Semiconductors. Input signals are compared to the tunable internal VCO of the IC,and depending on their compatibilty are mangled in a way that ostensibly is similar to a tradiational ring modulator circuit.

Sovereign is as much a sound *effector* as it is a sound *generator*, living comfortably between the two arbitrarily binary classes. Uses standard 9v center-NEGATIVE power supply (One Spot or similar)
