I'm trading off some EMGs for a Blackstar HT5 on Sunday night. I'll let you know how it works out for me if it's any help to you. I saw a schematic of it and there's a good bit of solid state in it(the first few gain stages, FX loop, EQ section and phase inverter), but I've read the same thing about the Gigmaster(haven't seen any gutshots so maybe rumour?). I did try an HT5 a bit ago and thought it was OK by itself, but it wasn't with my guitars, a boost of any kind and into the Blackstar 1x10 cab they sell with it. My first thoughts were to put an oversized tranny in it and boost the front end. Oversized. Ha. A 10W replacement tranny is oversized for that little creature. Sorry, can't comment on the clean channel, though it is foot switchable. I never even tried it out, was just looking to hear the gain character. The FearedSE vid on Youtube makes me think I can do a lot with a little adjustment on it and through decent speakers. Good luck on your search.
