What's interesting about the Supafuzz is that when it was produced by Sola Sound, it was just a re-branded MK II. Same circuit.
When Sola Sound ended the contract to produced them for Marshall, Marshall took over production in-house. That's when the 10 uf Input and Emitter caps came in. Interestingly enough though, they also removed the treble bleed cap at some point. However, it seems there was a period where they were still built with the treble bleed cap.
I've breadboarded both many, many times. The 10 uf/0.01 uf combo has a lot of "Ass" (for lack of a better term) and it should considering the treble rolloff at the input from the 0.01 uf. The 10uf/no treble bleed combo is interesting because it is actually a little brighter than the stock MK II but also just a touch fatter because of the bigger input and emitter caps.
