M658 Mother Mutant Desktop Noise Synthesizer

DesktopAnalog

$436

Called the Matriarch of MiniSynths by its creators, this all-analog beast unleashes a zoo of chaotic, ultra-harmonic noise from pure signal paths peaking at 20 volts point to point.

At its core, two oscillators offer switchable frequency ranges while three generators unlock 16 internal routing configs for wild sound sculpting. Six blast/mute buttons and a mode switch let you slam channels in or out with instant ferocity, backed by big playable knobs for volume, drive distortion, and external audio preamp with amplitude control—the incoming signal even loosely tracks to mess with the oscillators. Seven CV inputs plus a dedicated gate output invite modular mayhem, all packed into a compact cast-aluminum desktop chassis measuring 7.5 x 4.75 x 2 inches with worldwide power.

Noise enthusiasts dig its organic crunch and hands-on tactility for live experimentation, though some note the raw aggression demands taming in a mix.
