Key Features

  • Unique Dual-Filter Design: It uses two identical low-pass filters that sweep in opposite directions—one upward and one downward in frequency. This creates a more organic, vocal, and human quality to the envelope effect, producing richer and more complex tones.
  • Controls:
    • Blend: Adjusts the mix between the two filters.
    • Threshold: Sets the sensitivity to your playing dynamics (how easily the filter triggers based on attack strength).
    • Two Velocity knobs: Independent speed/sweep controls for the “up” and “down” filters, allowing fine-tuning for different playing styles.
  • True Bypass with Gig-Saver: Ensures your signal passes through even if the battery or power fails.
  • Compact and Road-Ready: Standard 9V DC power (not included), durable build, made in the USA.
