Rusty Hum is an electret condenser microphone module for explorations in room tone and feedback in the vein of the late Alvin Lucier, Masonna, and others. The small microphone is exposed to the outside world (albeit behind a mesh screen for protection) and introduces external sounds directly into the modular format. It features vactrol control of the microphone's level for CV-controlled room feedback or tremolo effects on the incoming audio.

This is (to our knowledge) the first implementation of a microphone built directly into a module, and we're happy to bring it to you.

Rusty Hum is 6HP and skiff-friendly.
