I love the BG simulation myself, but I reckon the Recto is the 'Metal' model, and the BG something more like a MkIV. With the gain throttled back to 3 or 4 you get a wonderful purring blues tone that I don't think a Recto could manage. I've wondered about the US Blues too, I reckon it's a Fender, possibly a Blues Deluxe or someting like that. OD I'd put as a Matchless Chieftan, and 'Lead' a Soldano SLO100. I wish modelling processor manufacturers wouldn't be so coy naming their amp models, but I guess that's copyright!
Effects are great, subtle, versatile and controllable, never harsh or overly digital.
Mine doesn't get much rough usage, but I'd guess it wouldn't notice - the thing's built like a tank.
I'm guessing Gibson13601 has named himself after his #1 axe - but I can confirm this thing sings with Fenders too - I play a USA Strat and a Squier Standard Tele, and it sounds equally delicious with both!
