RF-20 Resonant Filter
Korg MS-20 filter clone with dual LP/HP resonant filters, six knobs, and CV inputs for modular use.
FTelettronica is an Italian one-man shop in Isola del Liri, founded in 2008. They build faithful clones of rare and discontinued effects, using Alpha pots, Neutrik/Lumberg jacks, and a 2-year warranty.
The RF-20 is a Korg MS-20 filter/Frostwave Resonator clone with dual resonant filters: low-pass and high-pass, each with cutoff frequency and resonance controls, plus Input Level and Balance. Four 3.5mm CV jacks control LP Freq, LP Reso, HP Freq, and HP Reso for modular integration. Runs on 16V AC at 100mA. 548g, 150x132mm, powder-coated. True bypass.
The MS-20 filter is famous for its aggressive self-oscillating resonance. The 3.5mm CV inputs make this playable from Eurorack or other control voltage sources.
