The Harmonic Energizer Kit lets you build your own Systech Harmonic Energizer ™ replica. The Harmonic Energizer is a wide range notch filter: this pedal lets you dial ultra-narrow and resonant filtering, way beyond the range of most wahs. With extreme settings, the Harmonic Energizer even produces some overtones in weird ways well worth experimenting with. Another use of this versatile envelope filter is the “stuck wah“, useful if you want to boost some frequency of your instrument into high resonance. You can hear some examples of the sounds that can be achieved with the Harmonic Energizer in Frank Zappa ‘s “Shut Up and Play yer Guitar”.
Besides of the three knobs present in the original Harmonic Energizer, we’ve added an external Volume knob to easily set the output, as with different filter options the output volume can change slightly. The Bandwidth knob changes the sharpness of the frequency notch filter. Wide settings will deliver a more classic sound, while a narrower filter will produce a more aggressive tone. With Frequency and Gain you can set the gain and frequency to boost. If you want an incredibly fun to play effect pedal, we highly recommend you the Harmonic Energizer Kit!
