Fusion VCA

The core of Fusion VCA is Russion miniature penthode 1X24B with a power consumption comparable to an LED. We developed unique audio and tube control circuits, so Fusion VCA sounds like nothing youv’e heard before. Feedback adds harmonics to the original signal and acts similar to cutoff knob on VCFs and Deform knob controls amount of distortion in germanium diodes based circuit.

​​


Fusion VCF

24dB/12dB Fusion VCF is our take on the four pole lowpass filters. Each side of double triode drives signal between 2nd and 3rd stage of the filter, while germanium diodes are used to limit output signal. Result ultimately deep sounding VCF with unique character. Ingenious resonance volume compensation circuit and filter slope selection make this filter ideal for live performances. Bonus feature – 3 input mixer with dedicated mixer output.
