Gem HP & LP are small profile four-pole voltage controlled filters available in either low-pass or high-pass configuration. Behind the Gem filter’s modest appearance lurks a tonal beast with dual CV inputs for frequency and the ability to self oscillate at high resonance settings.
These compact VCFs are made with high-quality components including silver mica capacitors.
