"Sporting a red-sparkle metal enclosure and shiny gold knobs, the TK-01 Triskelion Harmonic Energizer ($349 retail/street N/A) takes its cue from vintage units such as the Maestro Parametric Filter and Systech Harmonic Energizer, allowing you to boost a particular frequency to the point of depravity for a plethora of tones ranging from beautiful to ugly to beautifully ugly. The TK-01's simple control layout sports an Energy control, which dials in the amount of boost, while Variant Mass selects the frequency to be boosted."
