I think it looks fabulous. The layout looks slick, and from a circuit perspective I don't see much in common with my pedals. He uses a different topology SMPS (I'm curious what it is, I've been eying more efficient ones for a while), he uses a pentode, I've only ever used dual triodes (we don't talk about Westinghouse). I'm sure if you looked at a schematic you could find things in common with some of my designs, but the same could be said with any tube preamp, there's really only so many ways to make a tube preamp and none of them are unique enough to be patentable.
I think the things I build are neat, but I can't take credit for introducing the world to SMPS for high-voltage generation in tube pedals. One example off the top of my head is Blackstar, who had a series of (relatively unsuccessful) high-voltage tube pedals back before I even started building pedals. I like to think my one reasonable contribution (and there still may be someone else that did it previously) is right-angle mounting the tube inside a relatively small enclosure. Again not something considered patentable, but something that I'm glad to see more people reaching for. Tube pedals don't need to be bulky and inconvenient.
It seems like a really cool product and it seems like the company also have some 500-series modules with similar tube topology, which I will reiterate looks great. Sometimes I look at a circuit board layout and cringe, and other times I look at it and applaud the designer that clearly knows what they are doing, and this definitely falls into the latter category. There's plenty of room in the market for more tube pedal builders, and I wish them the best.
