Well, got the 1987 and it's KILLER- Definitely has the "Friedman" feel to it. Marshall tone all the way but different than the Judge. I would say it's more of a JCM800 (with more gain than a stock JCM800) and the Judge is obviously a modded Plexi tone but they both have the Friedman/Marshall flavor to them. The Judge is smoother and more compressed, the 1987 is more open and raw with a fatter bottom end. If you're into the old Anthrax thrashy tones, this will nail it. Plenty of high end available to my ears and pronounced high mids, just like a Marshall. I stuck a TAD 7025 (my new favorite preamp tube for "some" modules, not all) in V1 and it got even bigger balls! One other difference, also noted by Steven Latch in previous posts, the 1987 can do mid gain much better than the Judge. It doesnt thin out like the Judge does when gain goes noon or lower so it will do a really convincing AC/DC type tone. Love both modules- plan on getting another Judge at some point. I love what Friedman has done with these two mods...
