OUT OF PRODUCTION! New version is on the way!

VCF with wide range of sonic possibilities. From warm, juicy sound to extreme, distorted and self-resonating screams.

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 and is available from Erica Synths SHOP or comes for free with purchase of 2 or more Erica Fusion modules. If you do so, do not order PSU, we'll add it to you order automatically. During checkout process, please, write a comment on what configuarion (110V or 220V) of the PSU you need, or if you allready have a Fusion PSU, that state that you do not need another.
