The Catwalk Ribbon Controller is Waveform's DIY Project #4. This attaches in a new way to your Eurorack system by going over top of existing modules and therefore taking up no extra HP. Super fun, kinda weird, and very touchy feely, this 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 are detailed in issue #4 and can be downloaded from the link to the right. Faceplate is black with silver.
Note: These come with M3 screws and standoffs, but if you need need M2.5, select that from the drop down menu.
