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)
