Could be Indy. The boost has a seperate fet but doesn't crackle but then it doesn't have any real overdrive, just more volume while the first drive fet wich is controled by the knob is there for the overdrive. I don't know much about that stuff.
To me the Box Of Rock (clone) feels and sounds more like an amp than a pedal but you do have to dig into the strings a little to get it to sound lively.
