I will write an article with instructions if there's interest. I bought one a couple of weeks ago, and the cleans were not clean enough for me. Also distorted tones were too dark, with too much emphasis on 'wrong' frequencies.
I'm a fan now... after removing three low-pass filters from the pre-amp, modifying bright cap, interstage filters and cathode caps. On the most Marshallesque settings it sounds stunningly close to my SC20H, but with bit more gain.
