This is similar to half a Make Noise Maths, so I built a couple.
All through hole, straightforward, no issues and not much to say about the build…haven’t done a through hole build in a while, and I definitely find them more laborious.
I like Kassutronics stuff, he often goes into detail about circuit function etc in the documentation. They’re excellent value for money as well. Less of a fan of the wood cut panels.
