Noisebug is a modular store based out of Pomona, Southern California. At Knobcon this year they were on hand to demo the Tangible Waves AE Modular system. The AE Modular system is its own format, it has those tiny little patchbays similar to the Korg Volca Modular or some of the Bastl Instruments stuff. This makes the systems a lot cheaper that some of the eurorack equivalents.
