Harmonic Energizer frequency booster Kit


If you like Zappa then you have to build the Harmonic Energizer! This wide range notch filter allows you to create some ultra-narrow and ultra-resonant filtering of your sound. You can even produce some overdrive and weird overtones! The Harmonic Energizer Kit is the perfect build to get a stuck wah tone, boosting a frequency into high resonance.

But the Harmonic Energizer can also be used as a frequency booster. By boosting just a range of frequencies you can give a thin guitar sound more presence, or get some highs boost for a brighter tone or to avoid treble loss. This version of the Harmonic Energizer also includes an external Volume knob to easily set the output level when trying different filter settings. An incredibly fun pedal to play with!
