From the vendor

Classic treble booster in a new compact form

Build doc:

Well this is an interesting one. The Iommic boost is based upon the DAM B13, which is based upon the classic Rangemaster. I stumbled upon the original schematic on FSB and now cannot find the original thread or reverse image search the image. The original used an OC81D and was positive ground, so I switched it to the more normal negative ground.
