Pros & Cons

👍 Pros

  • Offers a vintage-sounding 904B High Pass VCF module, recreating classic '70s tones.
  • Authentically reproduces the circuitry from the "Modular 55 & 35" Series, providing historical sonic accuracy.
  • Includes audio in and out connectors for straightforward integration into a Eurorack system.
  • Features three CV inputs for precise external control of the cutoff frequency, enhancing modulation possibilities.
