Dual SeM20 Eurorack Filter Module (Black)

Bubblesound Dual SeM20: Vintage Stereo Sculpting

The Dual SeM20 offers two channels of the iconic 12dB multi-mode filter circuit that defined the warm, airy sound of the 1970s. Each filter provides a dedicated Band Pass output alongside a unique state-variable output that can morph smoothly from Low Pass through Notch to High Pass. Unlike ladder filters, the SeM20 does not swallow your low-end when you crank the resonance, making it the perfect choice for deep, resonant basslines and shimmering polyphonic pads. With its dual design, it is the ultimate tool for true stereo analog filtering in a single module.
