Erica Fusion VCF is built around classical T bandpass filter topology with a tube working simultaneously as a preamplifier and filter feedback driver. As result you get a VCF with wide range of sonic possibilities from warm, juicy sound to extreme, distorted and self-resonating screams. With resonance fully CW you get sinewave tube VCO (not 1V/oct).

  • Two inputs (can be used as two input tube mixer)
  • Filter can self oscillate (produce tube-generated sinewave)
  • Two CV inputs
  • Inverted output
  • Warm & powerful tube sound

Erica Fusion modules have insignificant (max 15mA) power consumption from eurorack power supply unit (PSU), but they require separate, easy to install 6VAC PSU for tube heaters. Erica Fusion 6VAC PSU is designed to power up to 7 Erica Fusion modules.
