Godlyke, Inc. has the TWA TK-02 Triskelion Mk II. Triskelion is a variable-state band pass filter with adjustable gain and is based on the rare Systech Harmonic Energizer circuit as used by Jim Walsh, Greg Lake and Frank Zappa.
Since the Filter’s Q can be adjusted from very wide to extremely narrow widths, you can use it for harmonically focusing in a narrow frequency band, create glassy clean tones or boost the midrange for throaty solos.
The Triskelion Mk II has controls: for Gain and Output, Variant Mass control adjusts the filter’s frequency, Energy adjusts the Q of the Filter and the Energize footswitch works like a boost. In addition, there are two internal switches for selecting between two different filter ranges and to setup gain staging.
With an expression pedal input jack, 9-volt power supply, TWA’s S3™ relay-based True Bypass switching and a three-year warranty, the TWA Triskelion Mk II sells for $229 MAP.
