New Kits, 2022/11/11

Six new kits releasing today: Darkglass, Ross Comp, Tone Machine and more

Today, six more of our most popular PCB projects are graduating to full kits. They’re all themed around the sounds of the ’70s, with five of the original circuits actually released during that decade and the sixth (the Darkglass Microtubes) designed to emulate bass tones from that era.

We don’t yet have demo videos like we normally do with kit launches, but those should be coming before the end of the year—along with a few more surprises with regard to kits.
