OAM Time Machine
This is the most versatile delay I've seen so far, capable of much more than just "delay". The microcontroller also has quite a few unused CV inputs and outputs which you can access through an expansion module.
(also, I know everyone loves the huge sliders, but if we shrank them just a little, maybe we could fit the extra jacks at the bottom? pls don't kill me)
Even though the module isn't tiny, the versatility makes me think this would be an amazing choice for a smaller setup.
As far as I'm aware, there's no PCB available for this one, but the schematic is available on the github. Seems simple enough to hand wire.
