Microphonic Soundbox Mk2 Acoustic Experimental Instrument

Imagine scratching sandpaper or bowing taut springs to coax out eerie resonances from a wooden box that amplifies every nuance into haunting soundscapes. This acoustic experimental instrument invites you to explore body sounds in ways synths can't touch, blending raw physicality with clean amplification.

Housed in a sturdy 265 x 155 x 100 mm wooden enclosure weighing just 571 grams, it packs two internal contact microphones fed into battery-powered low-noise preamps offering around 100x gain. Individual gain knobs let you dial in each channel, while a Hi-Z input on the 6.3 mm jack bypasses the first mic for guitars, basses, or extra contact mics. Dual 1/4" outputs deliver mixed mono or separate stereo signals, complete with a handy attenuator for sensitive interfaces, plus soft rubber feet for grip and decoupling. Play the built-in carbon-strip kalimba, three springs, two metal rods, and sandpaper surface—or expand via the M3-threaded side strip and included mount for rubber bands, feathers, or found objects.

Since its 2023 release, sound designers have embraced it as a creative hub, praising the improved audio quality and frequency range over the original, though some note the need for a separate 9V battery.
