The Waveform 1U Ribbon Controller Passive Module is 34HP. It's super fun, kinda weird, and very touchy feely, and uses an LFO, offset, or something of the sort to power it, and we think it's the cats pajamas. The instructions on how to build this can be found on our Build Guide page. Faceplate is black with silver.
All Waveform 1U modules use the Intellijel size format.
