According to conventional wisdom, the violet version is a bit brighter and higher-gain than is normal for triangles and rams heads, so I'm expecting it will pair up well with darker-voiced amps.
I know nothing about the builder (I was planning to order one from North Effects, but he's sadly off the grid atm due to relocation and I'm not sure when he'll be making pedals again). It's going to be £25 plus postage and the enclosure is painted a nice fetching shade of purple, so as a last resort it's a Hammond box that I can use for future projects. I'm just curious as to how it sounds alongside my clones of the triangle, IC and Russian I guess.
