The Parsec Harmonic Enhancer is a pedal that is based on the Systech Harmonic Energizer, a popular filter and tone shaper used by notable musicians such as Frank Zappa, Adrian Belew, and others. The Harmonic Energizer utilized a state-variable filter, which was typically found in synthesizers, to achieve its frequency boost.

The Parsec is a faithful clone of the Harmonic Energizer, replicating its unique sound and functionality. It retains the innovative idea of using a state-variable filter in a guitar pedal, which was groundbreaking at the time. While the circuit does not include intentional clipping, the extreme frequency boost can cause the final op-amp to overload, resulting in a bit of fuzz at certain settings.

One additional feature that sets the Parsec apart from the original Harmonic Energizer is the inclusion of a volume control. This allows the user to adjust the output volume, enabling them to achieve unity volume even at higher bandwidth and gain settings.

Overall, the Parsec Harmonic Enhancer is a faithful recreation of the Systech Harmonic Energizer, offering guitarists the opportunity to achieve the same unique and innovative sound that was favored by renowned musicians like Frank Zappa, Adrian Belew, and others.
